-/**
- * read_barrier_depends - Flush all pending reads that subsequents reads
- * depend on.
- *
- * No data-dependent reads from memory-like regions are ever reordered
- * over this barrier.  All reads preceding this primitive are guaranteed
- * to access memory (but not necessarily other CPUs' caches) before any
- * reads following this primitive that depend on the data return by
- * any of the preceding reads.  This primitive is much lighter weight than
- * rmb() on most CPUs, and is never heavier weight than is
- * rmb().
- *
- * These ordering constraints are respected by both the local CPU
- * and the compiler.
- *
- * Ordering is not guaranteed by anything other than these primitives,
- * not even by data dependencies.  See the documentation for
- * memory_barrier() for examples and URLs to more information.
- *
- * For example, the following code would force ordering (the initial
- * value of "a" is zero, "b" is one, and "p" is "&a"):
- *
- * <programlisting>
- *	CPU 0				CPU 1
- *
- *	b = 2;
- *	memory_barrier();
- *	p = &b;				q = p;
- *					read_barrier_depends();
- *					d = *q;
- * </programlisting>
- *
- * because the read of "*q" depends on the read of "p" and these
- * two reads are separated by a read_barrier_depends().  However,
- * the following code, with the same initial values for "a" and "b":
- *
- * <programlisting>
- *	CPU 0				CPU 1
- *
- *	a = 2;
- *	memory_barrier();
- *	b = 3;				y = b;
- *					read_barrier_depends();
- *					x = a;
- * </programlisting>
- *
- * does not enforce ordering, since there is no data dependency between
- * the read of "a" and the read of "b".  Therefore, on some CPUs, such
- * as Alpha, "y" could be set to 3 and "x" to 0.  Use rmb()
- * in cases like this where there are no data dependencies.

-   An AVANTI *might* be an XL, and an XL has only 27 bits of ISA address
-   that get passed through the PCI<->ISA bridge chip. So we've gotta use
-   both windows to max out the physical memory we can DMA to. Sigh...
-
-   If we try a window at 0 for 1GB as a work-around, we run into conflicts
-   with ISA/PCI bus memory which can't be relocated, like VGA aperture and
-   BIOS ROMs. So we must put the windows high enough to avoid these areas.
-
-   We put window 1 at BUS 64Mb for 64Mb, mapping physical 0 to 64Mb-1,
-   and window 2 at BUS 1Gb for 1Gb, mapping physical 0 to 1Gb-1.
-   Yes, this does map 0 to 64Mb-1 twice, but only window 1 will actually
-   be used for that range (via virt_to_bus()).
-
-   Note that we actually fudge the window 1 maximum as 48Mb instead of 64Mb,
-   to keep virt_to_bus() from returning an address in the first window, for
-   a data area that goes beyond the 64Mb first DMA window.  Sigh...
-   The fudge factor MUST match with <asm/dma.h> MAX_DMA_ADDRESS, but
-   we can't just use that here, because of header file looping... :-(
-
-   Window 1 will be used for all DMA from the ISA bus; yes, that does
-   limit what memory an ISA floppy or sound card or Ethernet can touch, but
-   it's also a known limitation on other platforms as well. We use the
-   same technique that is used on INTEL platforms with similar limitation:
-   set MAX_DMA_ADDRESS and clear some pages' DMAable flags during mem_init().
-   We trust that any ISA bus device drivers will *always* ask for DMAable
-   memory explicitly via kmalloc()/get_free_pages() flags arguments.
-
-   Note that most PCI bus devices' drivers do *not* explicitly ask for
-   DMAable memory; they count on being able to DMA to any memory they
-   get from kmalloc()/get_free_pages(). They will also use window 1 for
-   any physical memory accesses below 64Mb; the rest will be handled by
-   window 2, maxing out at 1Gb of memory. I trust this is enough... :-)
-
-   We hope that the area before the first window is large enough so that
-   there will be no overlap at the top end (64Mb). We *must* locate the
-   PCI cards' memory just below window 1, so that there's still the
-   possibility of being able to access it via SPARSE space. This is
-   important for cards such as the Matrox Millennium, whose Xserver
-   wants to access memory-mapped registers in byte and short lengths.
-
-   Note that the XL is treated differently from the AVANTI, even though
-   for most other things they are identical. It didn't seem reasonable to
-   make the AVANTI support pay for the limitations of the XL. It is true,
-   however, that an XL kernel will run on an AVANTI without problems.
-
-   %%% All of this should be obviated by the ability to route
-   everything through the iommu.

- * Low Cost Alpha (LCA) definitions (these apply to 21066 and 21068,

- *	Hardware Reference Manual; Digital Equipment Corp.; May 1994;

-/*
- * NOTE: The LCA uses a Host Address Extension (HAE) register to access
- *	 PCI addresses that are beyond the first 27 bits of address
- *	 space.  Updating the HAE requires an external cycle (and
- *	 a memory barrier), which tends to be slow.  Instead of updating
- *	 it on each sparse memory access, we keep the current HAE value
- *	 cached in variable cache_hae.  Only if the cached HAE differs
- *	 from the desired HAE value do we actually updated HAE register.
- *	 The HAE register is preserved by the interrupt handler entry/exit
- *	 code, so this scheme works even in the presence of interrupts.
- *
- * Dense memory space doesn't require the HAE, but is restricted to
- * aligned 32 and 64 bit accesses.  Special Cycle and Interrupt
- * Acknowledge cycles may also require the use of the HAE.  The LCA
- * limits I/O address space to the bottom 24 bits of address space,
- * but this easily covers the 16 bit ISA I/O address space.
- */
-
-/*
- * NOTE 2! The memory operations do not set any memory barriers, as
- * it's not needed for cases like a frame buffer that is essentially
- * memory-like.  You need to do them by hand if the operations depend
- * on ordering.
- *
- * Similarly, the port I/O operations do a "mb" only after a write
- * operation: if an mb is needed before (as in the case of doing
- * memory mapped I/O first, and then a port I/O operation to the same
- * device), it needs to be done by hand.
- *
- * After the above has bitten me 100 times, I'll give up and just do
- * the mb all the time, but right now I'm hoping this will work out.
- * Avoiding mb's may potentially be a noticeable speed improvement,
- * but I can't honestly say I've tested it.
- *
- * Handling interrupts that need to do mb's to synchronize to
- * non-interrupts is another fun race area.  Don't do it (because if
- * you do, I'll have to do *everything* with interrupts disabled,
- * ugh).

- * ARC MMU provides 8-bit ASID (0..255) to TAG TLB entries, allowing entries
- * with same vaddr (different tasks) to co-exit. This provides for
- * "Fast Context Switch" i.e. no TLB flush on ctxt-switch
+ * ASID is managed per cpu, so task threads across CPUs can have different
+ * ASID. Global ASID management is needed if hardware supports TLB shootdown
+ * and/or shared TLB across cores, which ARC doesn't.
  *
- * Linux assigns each task a unique ASID. A simple round-robin allocation
- * of H/w ASID is done using software tracker @asid_cpu.
- * When it reaches max 255, the allocation cycle starts afresh by flushing
- * the entire TLB and wrapping ASID back to zero.
+ * Each task is assigned unique ASID, with a simple round-robin allocator
+ * tracked in @asid_cpu. When 8-bit value rolls over,a new cycle is started
+ * over from 0, and TLB is flushed
  *
  * A new allocation cycle, post rollover, could potentially reassign an ASID
  * to a different task. Thus the rule is to refresh the ASID in a new cycle.

- * e.g. MMU v2: K_READ bit is 8 and so is GLOBAL (possible because they live in

- *      while for PTE perspective, they are 8 and 9 respectively
- * with MMU v3: Most bits (except SHARED) represent the exact hardware pos

- *
- * Because it essentially checks if buffer end is within limit and @len is
- * non-ngeative, which implies that buffer start will be within limit too.
- *
- * The reason for rewriting being, for majority of cases, @len is generally
- * compile time constant, causing first sub-expression to be compile time
- * subsumed.
- *
- * The second part would generate weird large LIMMs e.g. (0x6000_0000 - 0x10),
- * so we check for TASK_SIZE using get_fs() since the addr_limit load from mem
- * would already have been done at this call site for __kernel_ok()

- *		I-Cache Aliasing in ARC700 VIPT caches (MMU v1-v3)
- *
- * ARC VIPT I-cache uses vaddr to index into cache and paddr to match the tag.
- * The orig Cache Management Module "CDU" only required paddr to invalidate a
- * certain line since it sufficed as index in Non-Aliasing VIPT cache-geometry.
- * Infact for distinct V1,V2,P: all of {V1-P},{V2-P},{P-P} would end up fetching
- * the exact same line.
- *
- * However for larger Caches (way-size > page-size) - i.e. in Aliasing config,
- * paddr alone could not be used to correctly index the cache.
+ * Cache Flush programming model
  *
- * ------------------
- * MMU v1/v2 (Fixed Page Size 8k)
- * ------------------
- * The solution was to provide CDU with these additonal vaddr bits. These
- * would be bits [x:13], x would depend on cache-geometry, 13 comes from
- * standard page size of 8k.
- * H/w folks chose [17:13] to be a future safe range, and moreso these 5 bits
- * of vaddr could easily be "stuffed" in the paddr as bits [4:0] since the
- * orig 5 bits of paddr were anyways ignored by CDU line ops, as they
- * represent the offset within cache-line. The adv of using this "clumsy"
- * interface for additional info was no new reg was needed in CDU programming
- * model.
+ * ARC700 MMUv3 I$ and D$ are both VIPT and can potentially alias.
+ * Programming model requires both paddr and vaddr irrespecive of aliasing
+ * considerations:
+ *  - vaddr in {I,D}C_IV?L
+ *  - paddr in {I,D}C_PTAG
  *
- * 17:13 represented the max num of bits passable, actual bits needed were
- * fewer, based on the num-of-aliases possible.
- * -for 2 alias possibility, only bit 13 needed (32K cache)
- * -for 4 alias possibility, bits 14:13 needed (64K cache)
+ * In HS38x (MMUv4), D$ is PIPT, I$ is VIPT and can still alias.
+ * Programming model is different for aliasing vs. non-aliasing I$
+ *  - D$ / Non-aliasing I$: only paddr in {I,D}C_IV?L
+ *  - Aliasing I$: same as ARC700 above (so MMUv3 routine used for MMUv4 I$)
  *
- * ------------------
- * MMU v3
- * ------------------
- * This ver of MMU supports variable page sizes (1k-16k): although Linux will
- * only support 8k (default), 16k and 4k.
- * However from hardware perspective, smaller page sizes aggravate aliasing
- * meaning more vaddr bits needed to disambiguate the cache-line-op ;
- * the existing scheme of piggybacking won't work for certain configurations.
- * Two new registers IC_PTAG and DC_PTAG inttoduced.
- * "tag" bits are provided in PTAG, index bits in existing IVIL/IVDL/FLDL regs
+ *  - If PAE40 is enabled, independent of aliasing considerations, the higher
+ *    bits needs to be written into PTAG_HI

-/*			Need for ARC MMU v2
- *
- * ARC700 MMU-v1 had a Joint-TLB for Code and Data and is 2 way set-assoc.
- * For a memcpy operation with 3 players (src/dst/code) such that all 3 pages
- * map into same set, there would be contention for the 2 ways causing severe
- * Thrashing.
- *
- * Although J-TLB is 2 way set assoc, ARC700 caches J-TLB into uTLBS which has
- * much higher associativity. u-D-TLB is 8 ways, u-I-TLB is 4 ways.
- * Given this, the thrasing problem should never happen because once the 3
- * J-TLB entries are created (even though 3rd will knock out one of the prev
- * two), the u-D-TLB and u-I-TLB will have what is required to accomplish memcpy
- *
- * Yet we still see the Thrashing because a J-TLB Write cause flush of u-TLBs.
- * This is a simple design for keeping them in sync. So what do we do?
- * The solution which James came up was pretty neat. It utilised the assoc
- * of uTLBs by not invalidating always but only when absolutely necessary.
- *
- * - Existing TLB commands work as before
- * - New command (TLBWriteNI) for TLB write without clearing uTLBs
- * - New command (TLBIVUTLB) to invalidate uTLBs.
- *
- * The uTLBs need only be invalidated when pages are being removed from the
- * OS page table. If a 'victim' TLB entry is being overwritten in the main TLB
- * as a result of a miss, the removed entry is still allowed to exist in the
- * uTLBs as it is still valid and present in the OS page table. This allows the
- * full associativity of the uTLBs to hide the limited associativity of the main
- * TLB.
- *
- * During a miss handler, the new "TLBWriteNI" command is used to load
- * entries without clearing the uTLBs.
- *
- * When the OS page table is updated, TLB entries that may be associated with a
- * removed page are removed (flushed) from the TLB using TLBWrite. In this
- * circumstance, the uTLBs must also be cleared. This is done by using the
- * existing TLBWrite command. An explicit IVUTLB is also required for those
- * corner cases when TLBWrite was not executed at all because the corresp
- * J-TLB entry got evicted/replaced.

+ * Remarks about the rationale behind the chosen mapping:

+ * - BPF_REG_{1,2,3,4} are the argument registers and must be mapped to
+ *   argument registers in ARCv2 ABI: r0-r7. The r7 registers is the last
+ *   argument register in the ABI. Therefore BPF_REG_5, as the fifth
+ *   argument, must be pushed onto the stack. This is a must for calling
+ *   in-kernel functions.
+ *
+ * - In ARCv2 ABI, the return value is in r0 for 32-bit results and (r1,r0)
+ *   for 64-bit results. However, because they're already used for BPF_REG_1,
+ *   the next available scratch registers, r8 and r9, are the best candidates
+ *   for BPF_REG_0. After a "call" to a(n) (in-kernel) function, the result
+ *   is "mov"ed to these registers. At a BPF_EXIT, their value is "mov"ed to
+ *   (r1,r0).
+ *   It is worth mentioning that scratch registers are the best choice for
+ *   BPF_REG_0, because it is very popular in BPF instruction encoding.
+ *
+ * - JIT_REG_TMP is an artifact needed to translate some BPF instructions.
+ *   Its life span is one single BPF instruction. Since during the
+ *   analyze_reg_usage(), it is not known if temporary registers are used,
+ *   it is mapped to ARC's scratch registers: r10 and r11. Therefore, they
+ *   don't matter in analysing phase and don't need saving. This temporary
+ *   register is added as yet another index in the bpf2arc array, so it will
+ *   unfold like the rest of registers during the code generation process.
+ *
+ * - Mapping of callee-saved BPF registers, BPF_REG_{6,7,8,9}, starts from
+ *   (r15,r14) register pair. The (r13,r12) is not a good choice, because
+ *   in ARCv2 ABI, r12 is not a callee-saved register and this can cause
+ *   problem when calling an in-kernel function. Theoretically, the mapping
+ *   could start from (r14,r13), but it is not a conventional ARCv2 register
+ *   pair. To have a future proof design, I opted for this arrangement.
+ *   If/when we decide to add ARCv2 instructions that do use register pairs,
+ *   the mapping, hopefully, doesn't need to be revisited.

+	 * Current implementation of "irq-dw-apb-ictl" driver doesn't work well
+	 * with stacked INTCs. In particular problem happens if its master INTC
+	 * not yet instantiated. See discussion here -
+	 * https://lore.kernel.org/lkml/54F6FE2C.7020309@synopsys.com
+	 *
+	 * So setup the first gpio block as a passive pass thru and hide it from
+	 * DT hardware topology - connect intc directly to cpu intc
+	 * The GPIO "wire" needs to be init nevertheless (here)
+	 *
+	 * One side adv is that peripheral interrupt handling avoids one nested
+	 * intc ISR hop
+	 *
+	 * According to HSDK User's Manual [1], "Table 2 Interrupt Mapping"
+	 * we have the following GPIO input lines used as sources of interrupt:
+	 * - GPIO[0] - Bluetooth interrupt of RS9113 module
+	 * - GPIO[2] - HAPS interrupt (on HapsTrak 3 connector)
+	 * - GPIO[3] - Audio codec (MAX9880A) interrupt
+	 * - GPIO[8-23] - Available on Arduino and PMOD_x headers
+	 * For now there's no use of Arduino and PMOD_x headers in Linux
+	 * use-case so we only enable lines 0, 2 and 3.

- * The 0xf1000000 is the default used by the recent, DT-capable, U-Boot
- * bootloaders provided by Marvell. It is used in recent versions of
- * DSM software provided by Synology. Nonetheless, some earlier boards
- * were delivered with an older version of u-boot that left internal
- * registers mapped at 0xd0000000. If you have such a device you will
- * not be able to directly boot a kernel based on this Device Tree. In
- * that case, the preferred solution is to update your bootloader (e.g.
- * by upgrading to latest version of DSM, or building a new one and
- * installing it from u-boot prompt) or adjust the Devive Tree
- * (s/0xf1000000/0xd0000000/ in 'ranges' below).

- * Note: this Device Tree assumes that the bootloader has remapped the
- * internal registers to 0xf1000000 (instead of the old 0xd0000000).
- * The 0xf1000000 is the default used by the recent, DT-capable, U-Boot
- * bootloaders provided by Marvell. It is used in recent versions of
- * DSM software provided by Synology. Nonetheless, some earlier boards
- * were delivered with an older version of u-boot that left internal
- * registers mapped at 0xd0000000. If you have such a device you will
- * not be able to directly boot a kernel based on this Device Tree. In
- * that case, the preferred solution is to update your bootloader (e.g.
- * by upgrading to latest version of DSM, or building a new one and
- * installing it from u-boot prompt) or adjust the Devive Tree
- * (s/0xf1000000/0xd0000000/ in 'ranges' below).

+ * In the reference design, GPIOV0 of AST2600-A2 EVB is connected to the
+ * power load switch that provides 3.3v to sdhci0 vdd, GPIOV1 is connected to
+ * a 1.8v and a 3.3v power load switch that provides signal voltage to
+ * sdhci0 bus.
+ * If GPIOV0 is active high, sdhci0 is enabled, otherwise, sdhci0 is disabled.
+ * If GPIOV1 is active high, 3.3v power load switch is enabled, sdhci0 signal
+ * voltage is 3.3v, otherwise, 1.8v power load switch will be enabled,
+ * sdhci0 signal voltage becomes 1.8v.
+ * AST2600-A2 EVB also supports toggling signal voltage for sdhci1.
+ * The design is the same as sdhci0, it uses GPIOV2 as power-gpio and GPIOV3
+ * as power-switch-gpio.
