2016-08-12emmc: support CMD23Haojian Zhuang
Support CMD23. When CMD23 is used, CMD12 could be avoided. Two scenarios: 1. CMD17 for single block, CMD18 + CMD12 for multiple blocks. 2. CMD23 + CMD18 for both single block and multiple blocks. The emmc_init() should initialize whether CMD23 is supported or not. Signed-off-by: Haojian Zhuang <haojian.zhuang@linaro.org>
2016-07-27GICv3: Fix the GICD_IROUTER offsetSoby Mathew
This patch fixes the offset of GICD_IROUTER register defined in gicv3.h. Although the GICv3 documention mentions that the offset for this register is 0x6100-0x7FD8, the offset calculation for an interrupt id `n` is : 0x6000 + 8n, where n >= 32 This requires the offset for GICD_IROUTER to be defined as 0x6000.

2016-07-18Rework type usage in Trusted FirmwareSoby Mathew
This patch reworks type usage in generic code, drivers and ARM platform files to make it more portable. The major changes done with respect to type usage are as listed below: * Use uintptr_t for storing address instead of uint64_t or unsigned long. * Review usage of unsigned long as it can no longer be assumed to be 64 bit. * Use u_register_t for register values whose width varies depending on whether AArch64 or AArch32. * Use generic C types where-ever possible. In addition to the above changes, this patch also modifies format specifiers in print invocations so that they are AArch64/AArch32 agnostic. Only files related to upcoming feature development have been reworked. Change-Id: I9f8c78347c5a52ba7027ff389791f1dad63ee5f8

2016-05-25CCN: Add API to query the PART0 ID from CCNSoby Mathew
This patch adds the API `ccn_get_part0_id` to query the PART0 ID from the PERIPHERAL_ID 0 register in the CCN driver. This ID allows to distinguish the variant of CCN present on the system and possibly enable dynamic configuration of the IP based on the variant. Also added an assert in `ccn_master_to_rn_id_map()` to ensure that the master map bitfield provided by the platform is within the expected interface id.

And it'll only copy the required data into buffer in io_block driver. So preparing an temporary buffer is required. When use io_block device, MAX_IO_BLOCK_DEVICES should be declared in platform_def.h. It's used to support multiple block devices. Signed-off-by: Haojian Zhuang <haojian.zhuang@linaro.org>
2016-04-12Use unsigned long long instead of uintptr_t in TZC400/DMC500 driversYatharth Kochar
Currently the `tzc400_configure_region` and `tzc_dmc500_configure_region` functions uses uintptr_t as the data type for `region_top` and `region_base` variables, which will be converted to 32/64 bits for AArch32/AArch64 respectively. But the expectation is to keep these addresses at least 64 bit. This patch modifies the data types to make it at least 64 bit by using unsigned long long instead of uintptr_t for the `region_top` and `region_base` variables. It also modifies the associated macros `_tzc##fn_name##_write_region_xxx` accordingly. Change-Id: I4e3c6a8a39ad04205cf0f3bda336c3970b15a28b

2016-03-31Add ARM CoreLink DMC-500 driver to program TrustZone protectionVikram Kanigiri
The ARM CoreLink DMC-500 Dynamic Memory Controller provides the programmable address region control of a TrustZone Address Space Controller. The access permissions can be defined for eight separate address regions plus a background or default region. This patch adds a DMC-500 driver to define address regions and program their access permissions as per ARM 100131_0000_02_en (r0p0) document. Change-Id: I9d33120f9480d742bcf7937e4b876f9d40c727e6
2016-03-31Refactor the ARM CoreLink TZC-400 driverVikram Kanigiri
TrustZone protection can be programmed by both memory and TrustZone address space controllers like DMC-500 and TZC-400. These peripherals share a similar programmer's view. Furthermore, it is possible to have multiple instances of each type of peripheral in a system resulting in multiple programmer's views. For example, on the TZC-400 each of the 4 filter units can be enabled or disabled for each region. There is a single set of registers to program the region attributes. On the DMC-500, each filter unit has its own programmer's view resulting in multiple sets of registers to program the region attributes. The layout of the registers is almost the same across all these variations. Hence the existing driver in `tzc400\tzc400.c` is refactored into the new driver in `tzc\tzc400.c`. The previous driver file is still maintained for compatibility and it is now deprecated. Change-Id: Ieabd0528e244582875bc7e65029a00517671216d
2016-03-31TBB: add non-volatile counter supportJuan Castillo
This patch adds support for non-volatile counter authentication to the Authentication Module. This method consists of matching the counter values provided in the certificates with the ones stored in the platform. If the value from the certificate is lower than the platform, the boot process is aborted. This mechanism protects the system against rollback. The TBBR CoT has been updated to include this method as part of the authentication process. Two counters are used: one for the trusted world images and another for the non trusted world images. ** NEW PLATFORM APIs (mandatory when TBB is enabled) ** int plat_get_nv_ctr(void *cookie, unsigned int *nv_ctr); This API returns the non-volatile counter value stored in the platform. The cookie in the first argument may be used to select the counter in case the platform provides more than one (i.e. TBSA compliant platforms must provide trusted and non-trusted counters). This cookie is specified in the CoT. int plat_set_nv_ctr(void *cookie, unsigned int nv_ctr); This API sets a new counter value. The cookie may be used to select the counter to be updated. An implementation of these new APIs for ARM platforms is also provided. The values are obtained from the Trusted Non-Volatile Counters peripheral. The cookie is used to pass the extension OID. This OID may be interpreted by the platform to know which counter must return. On Juno, The trusted and non-trusted counter values have been tied to 31 and 223, respectively, and cannot be modified. ** IMPORTANT ** THIS PATCH BREAKS THE BUILD WHEN TRUSTED_BOARD_BOOT IS ENABLED. THE NEW PLATFORM APIs INTRODUCED IN THIS PATCH MUST BE IMPLEMENTED IN ORDER TO SUCCESSFULLY BUILD TF. Change-Id: Ic943b76b25f2a37f490eaaab6d87b4a8b3cbc89a

2016-02-09Move private APIs in gic_common.h to a private headerSoby Mathew
This patch moves the private GIC common accessors from `gic_common.h` to a new private header file `gic_common_private.h`. This patch also adds additional comments to GIC register accessors to highlight the fact that some of them access register values that correspond to multiple interrupt IDs. The convention used is that the `set`, `get` and `clr` accessors access and modify the values corresponding to a single interrupt ID whereas the `read` and `write` GIC register accessors access the raw GIC registers and it could correspond to multiple interrupt IDs depending on the register accessed.

2016-02-09Fix GIC_IPRIORITYR setting in new driversSoby Mathew
The code to set the interrupt priority for secure interrupts in the new GICv2 and GICv3 drivers is incorrect. The setup code to configure interrupt priorities of secure interrupts, one interrupt at a time, used gicd_write_ipriorityr()/gicr_write_ipriority() function affecting 4 interrupts at a time. This bug did not manifest itself because all the secure interrupts were configured to the highest secure priority(0) during cold boot and the adjacent non secure interrupt priority would be configured later by the normal world. This patch introduces new accessors, gicd_set_ipriorityr() and gicr_set_ipriorityr(), for configuring priority one interrupt at a time and fixes the the setup code to use the new accessors.

Disable PL011 UART before configuring it
2016-01-21Disable PL011 UART before configuring itJuan Castillo
The PL011 TRM (ARM DDI 0183G) specifies that the UART must be disabled before any of the control registers are programmed. The PL011 driver included in TF does not disable the UART, so the initialization in BL2 and BL31 is violating this requirement (and potentially in BL1 if the UART is enabled after reset). This patch modifies the initialization function in the PL011 console driver to disable the UART before programming the control registers. Register clobber list and documentation updated.

2016-01-05Always build with '-pedantic'Sandrine Bailleux
By default ARM TF is built with the '-pedantic' compiler flag, which helps detecting violations of the C standard. However, the mbed TLS library and its associated authentication module in TF used to fail building with this compiler flag. As a workaround, the mbed TLS authentication module makefile used to set the 'DISABLE_PEDANTIC' TF build flag. The compiler errors flagged by '-pedantic' in the mbed TLS library have been fixed between versions 1.3.9 and 2.2.0 and the library now properly builds with this compiler flag. This patch fixes the remaining compiler errors in the mbed TLS authentication module in TF and unsets the 'DISABLE_PEDANTIC' TF build flag. This means that TF is now always built with '-pedantic'. In particular, this patch: * Removes the final semi-colon in REGISTER_COT() macro. This semi-colon was causing the following error message: drivers/auth/tbbr/tbbr_cot.c:544:23: error: ISO C does not allow extra ';' outside of a function [-Werror=pedantic] This has been fixed both in the mbed TLS authentication module as well as in the certificate generation tool. Note that the latter code didn't need fixing since it is not built with '-pedantic' but the change has been propagated for consistency. Also fixed the REGISTER_KEYS() and REGISTER_EXTENSIONS() macros, which were suffering from the same issue. * Fixes a pointer type. It was causing the following error message: drivers/auth/mbedtls/mbedtls_crypto.c: In function 'verify_hash': drivers/auth/mbedtls/mbedtls_crypto.c:177:42: error: pointer of type 'void *' used in arithmetic [-Werror=pointer-arith] Change-Id: I7b7a04ef711efd65e17b5be26990d1a0d940257d

2015-12-10Move up to mbed TLS 2.xJuan Castillo
The mbed TLS library has introduced some changes in the API from the 1.3.x to the 2.x releases. Using the 2.x releases requires some changes to the crypto and transport modules. This patch updates both modules to the mbed TLS 2.x API. All references to the mbed TLS library in the code or documentation have been updated to 'mbed TLS'. Old references to PolarSSL have been updated to 'mbed TLS'. User guide updated to use mbed TLS 2.2.0. NOTE: moving up to mbed TLS 2.x from 1.3.x is not backward compatible. Applying this patch will require an mbed TLS 2.x release to be used. Also note that the mbed TLS license changed to Apache version 2.0. Change-Id: Iba4584408653cf153091f2ca2ee23bc9add7fda4

De-feature PL011 UART driver to match generic UART spec
2015-12-10De-feature PL011 UART driver to match generic UART specJuan Castillo
The Server Base System Architecture document (ARM-DEN-0029) specifies a generic UART device. The programmer's view of this generic UART is a subset of the ARM PL011 UART. However, the current PL011 driver in Trusted Firmware uses some features that are outside the generic UART specification. This patch modifies the PL011 driver to exclude features outside the SBSA generic UART specification by setting the boolean build option 'PL011_GENERIC_UART=1'. Default value is 0 (use full PL011 features). User guide updated. Fixes ARM-software/tf-issues#216 Change-Id: I6e0eb86f9d69569bc3980fb57e70d6da5d91a737

2015-12-04Fix SP804 delay timer on FVPJuan Castillo
This patch fixes several issues with the SP804 delay timer on FVP: * By default, the SP804 dual timer on FVP runs at 32 KHz. In order to run the timer at 35 MHz (as specified in the FVP user manual) the Overwrite bit in the SP810 control register must be set. * The CLKMULT and CLKDIV definitions are mixed up: delta(us) = delta(ticks) * T(us) = delta(ticks) / f(MHz) From the delay function: delta_us = (delta * ops->clk_mult) / ops->clk_div; Matching both expressions: 1 / f(MHz) = ops->clk_mult / ops->clk_div And consequently: f(MHz) = ops->clk_div / ops->clk_mult Which, for a 35 MHz timer, translates to: ops->clk_div = 35 ops->clk_mult = 1 * The comment in the delay timer header file has been corrected: The ratio of the multiplier and the divider is the clock period in microseconds, not the frequency.

Fix TZC-400 peripheral detection
2015-11-27Fix TZC-400 peripheral detectionVikram Kanigiri
The TZC-400 driver implementation incorrectly uses the component ID registers to detect the TZC-400 peripheral. As all ARM peripherals share the same component ID, it doesn't allow to uniquely identify the TZC-400 peripheral. This patch fixes the TZC-400 driver by relying on the `part_number_0` and `part_number_1` fields in the `PID` registers instead. The `tzc_read_component_id` function has been replaced by `tzc_read_peripheral_id`, which reads the 'part_number' values and compares them with the TZC-400 peripheral ID. Also, it adds a debug assertion to detect when the TZC driver initialisation function is called multiple times. Change-Id: I35949f6501a51c0a794144cd1c3a6db62440dce6
2015-11-27Add a simple ARM SP805 watchdog driverJuan Castillo
Based on SP805 Programmer's model (ARM DDI 0270B). This driver provides three public APIs: void sp805_start(uintptr_t base, unsigned long ticks); void sp805_stop(uintptr_t base); void sp805_refresh(uintptr_t base, unsigned long ticks); Upon start, the watchdog starts counting down from the number of ticks specified. When the count reaches 0 an interrupt is triggered. The watchdog restarts counting down from the number of ticks specified. If the count reaches 0 again, the system is reset. A mechanism to handle the interrupt has not been implemented. Instead, the API to refresh the watchdog should be used instead to prevent a system reset.

This patch adds a driver for ARM GICv3 systems that need to run software stacks where affinity routing is enabled across all privileged exception levels for both security states. This driver is a partial implementation of the ARM Generic Interrupt Controller Architecture Specification, GIC architecture version 3.0 and version 4.0 (ARM IHI 0069A). The driver does not cater for legacy support of interrupts and asymmetric configurations. The existing GIC driver has been preserved unchanged. The common code for GICv2 and GICv3 systems has been refactored into a new file, `drivers/arm/gic/common/gic_common.c`. The corresponding header is in `include/drivers/arm/gic_common.h`. The driver interface is implemented in `drivers/arm/gic/v3/gicv3_main.c`. The corresponding header is in `include/drivers/arm/gicv3.h`. Helper functions are implemented in `drivers/arm/gic/v3/arm_gicv3_helpers.c` and are accessible through the `drivers/arm/gic/v3/gicv3_private.h` header.
