2019-08-01Switch AARCH32/AARCH64 to __aarch64__Julius Werner
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__.)

2019-01-04Sanitise includes across codebaseAntonio Nino Diaz
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.

2018-08-03Add atexit function to libcRoberto Vargas
We had exit but we didn't have atexit, and we were calling panic and tf_printf from exit, which generated a dependency from exit to them. Having atexit allows to set a different function pointer in every image. Change-Id: I95b9556d680d96249ed3b14da159b6f417da7661 Signed-off-by: Roberto Vargas <roberto.vargas@arm.com>
2018-02-28Fix MISRA rule 8.4 in common codeRoberto Vargas
Rule 8.4: A compatible declaration shall be visible when an object or function with external linkage is defined. Change-Id: I26e042cb251a6f9590afa1340fdac73e42f23979 Signed-off-by: Roberto Vargas <roberto.vargas@arm.com>
2017-07-12Fix order of #includesIsla Mitchell
This fix modifies the order of system includes to meet the ARM TF coding standard. There are some exceptions in order to retain header groupings, minimise changes to imported headers, and where there are headers within the #if and #ifndef statements.

2017-05-15AArch32: Add BL2U supportYatharth Kochar
Add support for firmware upgrade on AArch32. This patch has been tested on the FVP models. NOTE: Firmware upgrade on Juno AArch32 is not currently supported.

2015-12-09FWU: Add Generic BL2U FWU image support in BL2Yatharth Kochar
The Firmware Update (FWU) feature needs support for an optional secure world image, BL2U, to allow additional secure world initialization required by FWU, for example DDR initialization. This patch adds generic framework support to create BL2U. NOTE: A platform makefile must supply additional `BL2U_SOURCES` to build the bl2u target. A subsequent patch adds bl2u support for ARM platforms. Change-Id: If2ce036199bb40b39b7f91a9332106bcd4e25413
