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

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

sp_min: allow inclusion of a platform-specific linker script

2019-04-25T11:37:56Z

Similar to bl31 allow sp_min to also include a platform-specific linker script. This allows for example to place specific code in other memories of the system, like resume code in sram, while the main tf-a lives in ddr.

sp_min: make sp_min_warm_entrypoint public

2019-04-25T11:37:56Z

Similar to bl31_warm_entrypoint, sp_min-based platforms may need that for special resume handling. Therefore move it from the private header to the sp_min platform header. Signed-off-by: Heiko Stuebner Change-Id: I40d9eb3ff77cff88d47c1ff51d53d9b2512cbd3e

locks: linker variables to calculate per-cpu bakery lock size

2019-02-07T17:00:52Z

This patch introduces explicit linker variables to mark the start and end of the per-cpu bakery lock section to help bakery_lock_normal.c calculate the size of the section. This patch removes the previously used '__PERCPU_BAKERY_LOCK_SIZE__' linker variable to make the code uniform across GNU linker and ARM linker.

Correct typographical errors

2019-01-15T15:16:02Z

Corrects typos in core code, documentation files, drivers, Arm platforms and services. None of the corrections affect code; changes are limited to comments and other documentation. Change-Id: I5c1027b06ef149864f315ccc0ea473e2a16bfd1d Signed-off-by: Paul Beesley

Sanitise includes across codebase

2019-01-04T10:43:17Z

Enforce full include path for includes. Deprecate old paths. The following folders inside include/lib have been left unchanged: - include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH} The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them). For example, this patch had to be created because two headers were called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3a282 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca33988b9 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems. Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.

Standardise header guards across codebase

2018-11-08T10:20:19Z

All identifiers, regardless of use, that start with two underscores are reserved. This means they can't be used in header guards. The style that this project is now to use the full name of the file in capital letters followed by 'H'. For example, for a file called "uart_example.h", the header guard is UART_EXAMPLE_H. The exceptions are files that are imported from other projects: - CryptoCell driver - dt-bindings folders - zlib headers Change-Id: I50561bf6c88b491ec440d0c8385c74650f3c106e Signed-off-by: Antonio Nino Diaz

plat/arm: Support direct Linux kernel boot in AArch32

2018-11-05T17:11:03Z

This option allows the Trusted Firmware to directly jump to Linux kernel for aarch32 without the need of an intermediate loader such as U-Boot. Similar to AArch64 ARM_LINUX_KERNEL_AS_BL33 only available with RESET_TO_SP_MIN=1 as well as BL33 and DTB are preloaded in memory.

libc: Fix all includes in codebase

2018-08-22T09:26:05Z

The codebase was using non-standard headers. It is needed to replace them by the correct ones so that we can use the new libc headers. Change-Id: I530f71d9510cb036e69fe79823c8230afe890b9d Acked-by: Sumit Garg Signed-off-by: Antonio Nino Diaz
