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

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

Move defines in utils.h to utils_def.h to fix shared header compile issues

2017-04-29T15:30:05Z

utils.h is included in various header files for the defines in it. Some of the other header files only contain defines. This allows the header files to be shared between host and target builds for shared defines. Recently types.h has been included in utils.h as well as some function prototypes. Because of the inclusion of types.h conflicts exist building host tools abd these header files now. To solve this problem, move the defines to utils_def.h and have this included by utils.h and change header files to only include utils_def.h and not pick up the new types.h being introduced. Fixes ARM-software/tf-issues#461 Signed-off-by: Scott Branden Remove utils_def.h from utils.h This patch removes utils_def.h from utils.h as it is not required. And also makes a minor change to ensure Juno platform compiles. Change-Id: I10cf1fb51e44a8fa6dcec02980354eb9ecc9fa29

Changes to support execution in AArch32 state for JUNO

2017-04-20T14:05:21Z

Following steps are required to boot JUNO in AArch32 state: 1> BL1, in AArch64 state, loads BL2. 2> BL2, in AArch64 state, initializes DDR. Loads SP_MIN & BL33 (AArch32 executable)images. Calls RUN_IMAGE SMC to go back to BL1. 3> BL1 writes AArch32 executable opcodes, to load and branch at the entrypoint address of SP_MIN, at HI-VECTOR address and then request for warm reset in AArch32 state using RMR_EL3. This patch makes following changes to facilitate above steps: * Added assembly function to carry out step 3 above. * Added region in TZC that enables Secure access to the HI-VECTOR(0xFFFF0000) address space. * AArch32 image descriptor is used, in BL2, to load SP_MIN and BL33 AArch32 executable images. A new flag `JUNO_AARCH32_EL3_RUNTIME` is introduced that controls above changes. By default this flag is disabled. NOTE: BL1 and BL2 are not supported in AArch32 state for JUNO.

Fix ARM_BL31_IN_DRAM build

2017-04-03T17:59:22Z

Some header files using the ULL() macro were not directly including utils.h where the macro definition resides. As a consequence, a linker script with values using this macro did not see the macro definition and kept the "ULL()" call in the preprocessed file, which lead to link error. Files using ULL() macro now include utils.h directly. Change-Id: I433a7f36bd21a156c20e69bc2a2bb406140ebdf9 Signed-off-by: Douglas Raillard

ARM platforms: Enable xlat tables lib v2

2017-03-08T14:40:27Z

Modify ARM common makefile to use version 2 of the translation tables library and include the new header in C files. Simplify header dependencies related to this library to simplify the change. The following table contains information about the size increase in bytes for BL1 after applying this patch. The code has been compiled for different configurations of FVP in AArch64 mode with compiler GCC 4.9.3 20150413. The sizes have been calculated with the output of `nm` by adding the size of all regions and comparing the total size before and after the change. They are sumarized in the table below: text bss data total Release +660 -20 +88 +728 Debug +740 -20 +242 +962 Debug (LOG_LEVEL=50) +1120 -20 +317 +1417 Change-Id: I539e307f158ab71e3a8b771640001fc1bf431b29 Signed-off-by: Antonio Nino Diaz

Resolve build errors flagged by GCC 6.2

2017-01-26T13:47:37Z

With GCC 6.2 compiler, more C undefined behaviour is being flagged as warnings, which result in build errors in ARM TF build. The specific issue that this patch resolves is the use of (1 << 31), which is predominantly used in case statements, where 1 is represented as a signed int. When shifted to msb the behaviour is undefined. The resolution is to specify 1 as an unsigned int using a convenience macro ULL(). A duplicate macro MAKE_ULL() is replaced.
