* Standardise header guards across codebaseAntonio Nino Diaz2018-11-081-3/+3
| | | | | | | | | | | | | | | | | | 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>

* Introduce PSCI Library InterfaceSoby Mathew2016-07-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the PSCI Library interface. The major changes introduced are as follows: * Earlier BL31 was responsible for Architectural initialization during cold boot via bl31_arch_setup() whereas PSCI was responsible for the same during warm boot. This functionality is now consolidated by the PSCI library and it does Architectural initialization via psci_arch_setup() during both cold and warm boots. * Earlier the warm boot entry point was always `psci_entrypoint()`. This was not flexible enough as a library interface. Now PSCI expects the runtime firmware to provide the entry point via `psci_setup()`. A new function `bl31_warm_entrypoint` is introduced in BL31 and the previous `psci_entrypoint()` is deprecated. * The `smc_helpers.h` is reorganized to separate the SMC Calling Convention defines from the Trusted Firmware SMC helpers. The former is now in a new header file `smcc.h` and the SMC helpers are moved to Architecture specific header. * The CPU context is used by PSCI for context initialization and restoration after power down (PSCI Context). It is also used by BL31 for SMC handling and context management during Normal-Secure world switch (SMC Context). The `psci_smc_handler()` interface is redefined to not use SMC helper macros thus enabling to decouple the PSCI context from EL3 runtime firmware SMC context. This enables PSCI to be integrated with other runtime firmware using a different SMC context. NOTE: With this patch the architectural setup done in `bl31_arch_setup()` is done as part of `psci_setup()` and hence `bl31_platform_setup()` will be invoked prior to architectural setup. It is highly unlikely that the platform setup will depend on architectural setup and cause any failure. Please be be aware of this change in sequence.

* Remove all checkpatch errors from codebaseJuan Castillo2014-06-241-1/+1
| | | | | | | | Exclude stdlib files because they do not follow kernel code style. Fixes ARM-software/tf-issues#73 Change-Id: I4cfafa38ab436f5ab22c277cb38f884346a267ab
* Further renames of platform porting functionsDan Handley2014-05-271-6/+0
| | | | | | | | | Rename the ic_* platform porting functions to plat_ic_* to be consistent with the other functions in platform.h. Also rename bl31_get_next_image_info() to bl31_plat_get_next_image_ep_info() and remove the duplicate declaration in bl31.h. Change-Id: I4851842069d3cff14c0a468daacc0a891a7ede84
* Move BL porting functions into platform.hDan Handley2014-05-231-4/+0
| | | | | | | | | | | | | | | 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
* Remove unused data declarationsDan Handley2014-05-231-5/+0
| | | | | | | Some data variables were declared but not used. These have been removed. Change-Id: I038632af3c32d88984cd25b886c43ff763269bf9
* Remove extern keyword from function declarationsDan Handley2014-05-231-11/+10
| | | | | | | Function declarations implicitly have external linkage so do not need the extern keyword. Change-Id: Ia0549786796d8bf5956487e8996450a0b3d79f32
* Rework memory information passing to BL3-x imagesVikram Kanigiri2014-05-221-3/+4
| | | | | | | | | | | | | | | | | | 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
* Populate BL31 input parameters as per new specVikram Kanigiri2014-05-221-2/+2
| | | | | | | | | | | | | | | | | | 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
* Reduce deep nesting of header filesDan Handley2014-05-061-5/+12
| | | | | | | | | | | | | | 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
* Always use named structs in header filesDan Handley2014-05-061-4/+4
| | | | | | | | | | | | | | | | | 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
* Separate BL functions out of arch.hDan Handley2014-05-061-0/+1
| | | | | | | | | Move the BL function prototypes out of arch.h and into the appropriate header files to allow more efficient header file inclusion. Create new BL private header files where there is no sensible existing header file. Change-Id: I45f3e10b72b5d835254a6f25a5e47cf4cfb274c3
* Move include and source files to logical locationsDan Handley2014-05-061-0/+53
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
