Add Broadcom's code for bcm63xx support

2021-12-24T12:15:12Z

This includes all bcm63xx families (some of them don't follow that naming schema - like BCM4908). All that code has been extracted from the RAXE500_RAXE450-V1.0.8.70_GPL_release.zip . Signed-off-by: Rafał Miłecki

Fix the CAS spinlock implementation

2019-10-04T08:19:35Z

Make the spinlock implementation use ARMv8.1-LSE CAS instruction based on a platform build option. The CAS-based implementation used to be unconditionally selected for all ARM8.1+ platforms. The previous CAS spinlock implementation had a bug wherein the spin_unlock() implementation had an `sev` after `stlr` which is not sufficient. A dsb is needed to ensure that the stlr completes prior to the sev. Having a dsb is heavyweight and a better solution would be to use load exclusive semantics to monitor the lock and wake up from wfe when a store happens to the lock. The patch implements the same.

* changes: Remove RSA PKCS#1 v1.5 support from cert_tool Add documentation for new KEY_SIZE option Add cert_create tool support for RSA key sizes Support larger RSA key sizes when using MBEDTLS

Add cert_create tool support for RSA key sizes

2019-09-12T14:27:41Z

cert_tool is now able to accept a command line option for specifying the key size. It now supports the following options: 1024, 2048 (default), 3072 and 4096. This is also modifiable by TFA using the build flag KEY_SIZE. Change-Id: Ifadecf84ade3763249ee8cc7123a8178f606f0e5 Signed-off-by: Justin Chadwell

Invalidate dcache build option for bl2 entry at EL3

2019-09-12T12:36:31Z

Some of the platform (ie. Agilex) make use of CCU IPs which will only be initialized during bl2_el3_early_platform_setup. Any operation to the cache beforehand will crash the platform. Hence, this will provide an option to skip the data cache invalidation upon bl2 entry at EL3 Signed-off-by: Hadi Asyrafi Change-Id: I2c924ed0589a72d0034714c31be8fe57237d1f06

* changes: Add documentation for CTX_INCLUDE_MTE_REGS Enable MTE support in both secure and non-secure worlds

Add UBSAN support and handlers

2019-09-11T13:15:54Z

This patch adds support for the Undefined Behaviour sanitizer. There are two types of support offered - minimalistic trapping support which essentially immediately crashes on undefined behaviour and full support with full debug messages. The full support relies on ubsan.c which has been adapted from code used by OPTEE. Change-Id: I417c810f4fc43dcb56db6a6a555bfd0b38440727 Signed-off-by: Justin Chadwell

Enable MTE support in both secure and non-secure worlds

2019-09-09T15:23:33Z

This patch adds support for the new Memory Tagging Extension arriving in ARMv8.5. MTE support is now enabled by default on systems that support at EL0. To enable it at ELx for both the non-secure and the secure world, the compiler flag CTX_INCLUDE_MTE_REGS includes register saving and restoring when necessary in order to prevent register leakage between the worlds.

Switch AARCH32/AARCH64 to aarch64

2019-08-01T20:45:03Z

NOTE: AARCH32/AARCH64 macros are now deprecated in favor of __aarch64__. All common C compilers pre-define the same macros to signal which architecture the code is being compiled for: __arm__ for AArch32 (or earlier versions) and __aarch64__ for AArch64. There's no need for TF-A to define its own custom macros for this. In order to unify code with the export headers (which use __aarch64__ to avoid another dependency), let's deprecate the AARCH32 and AARCH64 macros and switch the code base over to the pre-defined standard macro. (Since it is somewhat unintuitive that __arm__ only means AArch32, let's standardize on only using __aarch64__.) Change-Id: Ic77de4b052297d77f38fc95f95f65a8ee70cf200 Signed-off-by: Julius Werner

Replace ASSEMBLY with compiler-builtin ASSEMBLER

2019-08-01T20:14:12Z

NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__. All common C compilers predefine a macro called __ASSEMBLER__ when preprocessing a .S file. There is no reason for TF-A to define it's own __ASSEMBLY__ macro for this purpose instead. To unify code with the export headers (which use __ASSEMBLER__ to avoid one extra dependency), let's deprecate __ASSEMBLY__ and switch the code base over to the predefined standard.
