2018-11-08Standardise header guards across codebaseAntonio Nino Diaz
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 <antonio.ninodiaz@arm.com>

Rule 8.5: An external object or function shall be declared once in one and only one file. Change-Id: I7c3d4ec7d3ba763fdb4600008ba10b4b93ecdfce Signed-off-by: Roberto Vargas <roberto.vargas@arm.com>

2014-05-23Move BL porting functions into platform.hDan Handley
Some platform porting functions were in BL specific header files. These have been moved to platform.h so that all porting functions are in the same place. The functions are now grouped by BL. Obsolete BL headers files have been removed. Also, the weak declaration of the init_bl2_mem_layout() function has been moved out the header file and into the source file (bl_common.c) using the more succinct #pragma syntax. This mitigates the risk of 2 weak definitions being created and the wrong one being picked up by the compiler. Change-Id: Ib19934939fd755f3e5a5a5bceec88da684308a83
2014-05-23Remove unused data declarationsDan Handley
Some data variables were declared but not used. These have been removed. Change-Id: I038632af3c32d88984cd25b886c43ff763269bf9
2014-05-23Remove extern keyword from function declarationsDan Handley
Function declarations implicitly have external linkage so do not need the extern keyword. Change-Id: Ia0549786796d8bf5956487e8996450a0b3d79f32
2014-05-22Rework memory information passing to BL3-x imagesVikram Kanigiri
The issues addressed in this patch are: 1. Remove meminfo_t from the common interfaces in BL3-x, expecting that platform code will find a suitable mechanism to determine the memory extents in these images and provide it to the BL3-x images. 2. Remove meminfo_t and bl31_plat_params_t from all FVP BL3-x code as the images use link-time information to determine memory extents. meminfo_t is still used by common interface in BL1/BL2 for loading images Change-Id: I4e825ebf6f515b59d84dc2bdddf6edbf15e2d60f
2014-05-22Populate BL31 input parameters as per new specVikram Kanigiri
This patch is based on spec published at https://github.com/ARM-software/tf-issues/issues/133 It rearranges the bl31_args struct into bl31_params and bl31_plat_params which provide the information needed for Trusted firmware and platform specific data via x0 and x1 On the FVP platform BL3-1 params and BL3-1 plat params and its constituents are stored at the start of TZDRAM. The information about memory availability and size for BL3-1, BL3-2 and BL3-3 is moved into platform specific data. Change-Id: I8b32057a3d0dd3968ea26c2541a0714177820da9
2014-05-06Reduce deep nesting of header filesDan Handley
Reduce the number of header files included from other header files as much as possible without splitting the files. Use forward declarations where possible. This allows removal of some unnecessary "#ifndef __ASSEMBLY__" statements. Also, review the .c and .S files for which header files really need including and reorder the #include statements alphabetically. Fixes ARM-software/tf-issues#31 Change-Id: Iec92fb976334c77453e010b60bcf56f3be72bd3e
2014-05-06Always use named structs in header filesDan Handley
Add tag names to all unnamed structs in header files. This allows forward declaration of structs, which is necessary to reduce header file nesting (to be implemented in a subsequent commit). Also change the typedef names across the codebase to use the _t suffix to be more conformant with the Linux coding style. The coding style actually prefers us not to use typedefs at all but this is considered a step too far for Trusted Firmware. Also change the IO framework structs defintions to use typedef'd structs to be consistent with the rest of the codebase. Change-Id: I722b2c86fc0d92e4da3b15e5cab20373dd26786f
2014-05-06Move include and source files to logical locationsDan Handley
Move almost all system include files to a logical sub-directory under ./include. The only remaining system include directories not under ./include are specific to the platform. Move the corresponding source files to match the include directory structure. Also remove pm.h as it is no longer used. Change-Id: Ie5ea6368ec5fad459f3e8a802ad129135527f0b3
