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

Explicitly disable the SPME bit in MDCR_EL3

2019-10-07T10:50:07Z

Currently the MDCR_EL3 initialisation implicitly disables MDCR_EL3.SPME by using mov_imm. This patch makes the SPME bit more visible by explicitly disabling it and documenting its use in different versions of the architecture.

Add missing support for BL2_AT_EL3 in XIP memory

2019-10-02T07:06:39Z

Add the missing flag for aarch32 XIP memory mode. It was previously added in aarch64 only. Minor: Correct the aarch64 missing flag. Signed-off-by: Lionel Debieve Change-Id: Iac0a7581a1fd580aececa75f97deb894858f776f

AArch32: Disable Secure Cycle Counter

2019-09-26T15:36:02Z

This patch changes implementation for disabling Secure Cycle Counter. For ARMv8.5 the counter gets disabled by setting SDCR.SCCD bit on CPU cold/warm boot. For the earlier architectures PMCR register is saved/restored on secure world entry/exit from/to Non-secure state, and cycle counting gets disabled by setting PMCR.DP bit. In 'include\aarch32\arch.h' header file new ARMv8.5-PMU related definitions were added. Change-Id: Ia8845db2ebe8de940d66dff479225a5b879316f8 Signed-off-by: Alexei Fedorov

Refactor ARMv8.3 Pointer Authentication support code

2019-09-13T13:11:59Z

This patch provides the following features and makes modifications listed below: - Individual APIAKey key generation for each CPU. - New key generation on every BL31 warm boot and TSP CPU On event. - Per-CPU storage of APIAKey added in percpu_data[] of cpu_data structure. - `plat_init_apiakey()` function replaced with `plat_init_apkey()` which returns 128-bit value and uses Generic timer physical counter value to increase the randomness of the generated key. The new function can be used for generation of all ARMv8.3-PAuth keys - ARMv8.3-PAuth specific code placed in `lib\extensions\pauth`. - New `pauth_init_enable_el1()` and `pauth_init_enable_el3()` functions generate, program and enable APIAKey_EL1 for EL1 and EL3 respectively; pauth_disable_el1()` and `pauth_disable_el3()` functions disable PAuth for EL1 and EL3 respectively; `pauth_load_bl31_apiakey()` loads saved per-CPU APIAKey_EL1 from cpu-data structure. - Combined `save_gp_pauth_registers()` function replaces calls to `save_gp_registers()` and `pauth_context_save()`; `restore_gp_pauth_registers()` replaces `pauth_context_restore()` and `restore_gp_registers()` calls. - `restore_gp_registers_eret()` function removed with corresponding code placed in `el3_exit()`. - Fixed the issue when `pauth_t pauth_ctx` structure allocated space for 12 uint64_t PAuth registers instead of 10 by removal of macro CTX_PACGAKEY_END from `include/lib/el3_runtime/aarch64/context.h` and assigning its value to CTX_PAUTH_REGS_END. - Use of MODE_SP_ELX and MODE_SP_EL0 macro definitions in `msr spsel` instruction instead of hard-coded values. - Changes in documentation related to ARMv8.3-PAuth and ARMv8.5-BTI.

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

Merge changes from topic "jc/mte_enable" into integration

* 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.
