Add support for the Variscite VAR_SOM-MX6UL SoM with:
- NXP i.MX6 UltraLite SoC
- 128–1024 MB DDR3L
- 8–128 GB eMMC
- 128–512 MB SLC NAND
- Camera Interface
- LVDS / Parallel RGB interfaces (not configured)
- Touch controller (not configured)
- Ethernet RMII interface (not configured)
- On-SoM Wi-Fi/Bluetooth with CYW43353 on SDIO Module (not configured)
- SD/MMC/SDIO interface
- USB Host + USB OTG interface
- I2C interfaces
- SPI interfaces
- PCI-Express 2.0 interface
- on-SoM Audio Codec (not configured)
- S/PDIF interface (not configured)
Product website: https://www.variscite.com/product/system-on-module-som/cortex-a7/var-som-6ul-nxp-imx6ul-6ull-6ulz
Support is handled with a SoM-centric dtsi exporting the default
interfaces along the default pinmuxing to be enabled by the board dts
file.
I tested this on a VAR-SOM-6UL_G2_700C_512R_8N_IT_REV1.3A, which is why
some of the features above are mentioned as "not configured" (I couldn't
test them).
This file is based on the one provided by Variscite on their own kernel,
but adapted for mainline.

Unused 'static const' variables cause a warning when building with
W=1, and imx53_suspend_sz has a definition for this as an
alternative when CONFIG_SUSPEND is disabled:
In file included from arch/arm/mach-imx/cpu.c:9:
arch/arm/mach-imx/common.h:101:18: error: 'imx53_suspend_sz' defined but not used [-Werror=unused-const-variable=]
It's still referenced though, so mark it as __maybe_unused, so
the one user can address the dummy copy and other files that include
the header don't produce a warning.

TQMa6UL1 has only one FEC which needs to be disabled as one of the last

defaults from imx6ul.dtsi will be applied again.

that also 'select GENERIC_IRQ_CHIP' and statistically there is almost
always one of them enabled.

To fix it, do not rely on whether 'ptl' is equal to decide whether to hold
the pte lock, but decide it by whether CONFIG_SPLIT_PTE_PTLOCKS is
enabled. In addition, if two vmas map to the same PTE page, there is no
need to hold the pte lock again, otherwise a deadlock will occur. Just
add the need_lock parameter to let adjust_pte() know this information.

New clocks are saved to enable ULP0/ULP1 for SAMA7D65 because this SoC has a
total of 9 main clocks that need to be saved for ULP0/ULP1 mode.
Add mcks member to at91_pm_data, this will be used to determine
how many main clocks need to be saved. In the pm_mcks variable will also make
sure that no unnecessary clock settings are written during
mck_ps_restore.

Add config check that enables Backup mode for SAMA7D65 SoC.
Add SHDWC_SR read to clear the status bits once finished exiting backup
mode. This is only for SAMA7D65 SoCs. The SHDWC status register
needs to be cleared after exiting backup mode to clear the wake up pin
status.

For sama7g5 and sama7d65 backup mode, we encountered a "ZQ calibrate error"
during recalibrating the impedance in BootStrap.
We found that the impedance value saved in at91_suspend_finish() before
the DDR entered self-refresh mode did not match the resistor values. The
ZDATA field in the DDR3PHY_ZQ0CR0 register uses a modified gray code to
select the different impedance setting.
But these gray code are incorrect, a workaournd from design team fixed the
bug in the calibration logic. The ZDATA contains four independent impedance
elements, but the algorithm combined the four elements into one. The elements
were fixed using properly shifted offsets.

The ARCH_MAY_HAVE patch missed arm64, mips and s390. But it may
also lead to arch options being enabled but ineffective because
of modular/built-in conflicts.
As the primary user of all these options wireguard is selecting
the arch options anyway, make the same selections at the lib/crypto
option level and hide the arch options from the user.
Instead of selecting them centrally from lib/crypto, simply set
the default of each arch option as suggested by Eric Biggers.
Change the Crypto API generic algorithms to select the top-level
lib/crypto options instead of the generic one as otherwise there
is no way to enable the arch options (Eric Biggers). Introduce a
set of INTERNAL options to work around dependency cycles on the
CONFIG_CRYPTO symbol.
