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

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

Mark GICV3, CCI and CCN boot time code as init

Fix type of `unsigned long` constants

2017-09-21T11:03:53Z

The type `unsigned long` is 32 bit wide in AArch32, but 64 bit wide in AArch64. This is inconsistent and that's why we avoid using it as per the Coding Guidelines. This patch changes all `UL` occurrences to `U` or `ULL` depending on the context so that the size of the constant is clear. This problem affected the macro `BIT(nr)`. As long as this macro is used to fill fields of registers, that's not a problem, since all registers are 32 bit wide in AArch32 and 64 bit wide in AArch64. However, if the macro is used to fill the fields of a 64-bit integer, it won't be able to set the upper 32 bits in AArch32. By changing the type of this macro to `unsigned long long` the behaviour is always the same regardless of the architecture, as this type is 64-bit wide in both cases. Some Tegra platform files have been modified by this patch. Change-Id: I918264c03e7d691a931f0d1018df25a2796cc221 Signed-off-by: Antonio Nino Diaz

Use SPDX license identifiers

2017-05-03T08:39:28Z

To make software license auditing simpler, use SPDX[0] license identifiers instead of duplicating the license text in every file. NOTE: Files that have been imported by FreeBSD have not been modified. [0]: https://spdx.org/ Change-Id: I80a00e1f641b8cc075ca5a95b10607ed9ed8761a Signed-off-by: dp-arm

Control inclusion of helper code used for asserts

2017-04-20T08:59:12Z

Many asserts depend on code that is conditionally compiled based on the DEBUG define. This patch modifies the conditional inclusion of such code so that it is based on the ENABLE_ASSERTIONS build option. Change-Id: I6406674788aa7e1ad7c23d86ce94482ad3c382bd Signed-off-by: Antonio Nino Diaz
