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.

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

tlkd: support new TLK SMCs

2019-01-31T16:46:54Z

This patch adds support to handle following TLK SMCs: {TLK_SS_REGISTER_HANDLER, TLK_REGISTER_NS_DRAM_RANGES, TLK_SET_ROOT_OF_TRUST} These SMCs need to be supported in ATF in order to forward them to TLK. Otherwise, these functionalities won't work. Brief: TLK_SS_REGISTER_HANDLER: This SMC is issued by TLK Linux Driver to set up secure storage buffers. TLK_REGISTER_NS_DRAM_RANGES: Cboot performs this SMC during boot to pass NS memory ranges to TLK. TLK_SET_ROOT_OF_TRUST: Cboot performs this SMC during boot to pass Verified Boot parameters to TLK.

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

Remove deprecated early platform setup interfaces

The affected interfaces are bl31_early_platform_setup(), sp_min_early_platform_setup() and bl2_early_platform_setup(). Change-Id: I50c01ec68bcbe97fe4e5d101bcd0f763358b8e1e Signed-off-by: Antonio Nino Diaz

Introduce the new BL handover interface

2018-02-26T16:31:10Z

This patch introduces a new BL handover interface. It essentially allows passing 4 arguments between the different BL stages. Effort has been made so as to be compatible with the previous handover interface. The previous blx_early_platform_setup() platform API is now deprecated and the new blx_early_platform_setup2() variant is introduced. The weak compatiblity implementation for the new API is done in the `plat_bl_common.c` file. Some of the new arguments in the new API will be reserved for generic code use when dynamic configuration support is implemented. Otherwise the other registers are available for platform use.

spd: tlkd: support for "NS memory ranges" function ID

bl32: add secure interrupt handling in AArch32 sp_min

2017-08-09T13:48:53Z

Add support for a minimal secure interrupt service in sp_min for the AArch32 implementation. Hard code that only FIQs are handled. Introduce bolean build directive SP_MIN_WITH_SECURE_FIQ to enable FIQ handling from SP_MIN. Configure SCR[FIQ] and SCR[FW] from generic code for both cold and warm boots to handle FIQ in secure state from monitor. Since SP_MIN architecture, FIQ are always trapped when system executes in non secure state. Hence discard relay of the secure/non-secure state in the FIQ handler.
