Separate BL functions out of arch.h 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

Standardise header guards across codebase 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>

libc: Fix all includes in codebase The codebase was using non-standard headers. It is needed to replace them by the correct ones so that we can use the new libc headers.

#include <stdint.h>
Sanitise includes across codebase 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&#39;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 (&#34;Fix gpio includes of mt8173 platform to avoid collision.&#34;). More recently, this patch has had similar problems: 46f9b2c3a282 (&#34;drivers: add tzc380 support&#34;). This problem was introduced in commit 4ecca33988b9 (&#34;Move include and source files to logical locations&#34;). At that time, there weren&#39;t too many headers so it wasn&#39;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.

#include <common/bl_common.h>
Remove concept of top/bottom image loading This concept is no longer required since we now support loading of images at fixed addresses only. The image loader now automatically detects the position of the image inside the current memory layout and updates the layout such that memory fragmentation is minimised. The &#39;attr&#39; field of the meminfo data structure, which used to hold the bottom/top loading information, has been removed. Also the &#39;next&#39; field has been removed as it wasn&#39;t used anywhere. The &#39;init_bl2_mem_layout()&#39; function has been moved out of common code and put in BL1-specific code. It has also been renamed into &#39;bl1_init_bl2_mem_layout&#39;. Fixes ARM-software/tf-issues#109 Change-Id: I3f54642ce7b763d5ee3b047ad0ab59eabbcf916d

Add descriptor based image management support in BL1 As of now BL1 loads and execute BL2 based on hard coded information provided in BL1. But due to addition of support for upcoming Firmware Update feature, BL1 now require more flexible approach to load and run different images using information provided by the platform. This patch adds new mechanism to load and execute images based on platform provided image id&#39;s. BL1 now queries the platform to fetch the image id of the next image to be loaded and executed. In order to achieve this, a new struct image_desc_t was added which holds the information about images, such as: ep_info and image_info. This patch introduces following platform porting functions: unsigned int bl1_plat_get_next_image_id(void); This is used to identify the next image to be loaded and executed by BL1. struct image_desc *bl1_plat_get_image_desc(unsigned int image_id); This is used to retrieve the image_desc for given image_id. void bl1_plat_set_ep_info(unsigned int image_id, struct entry_point_info *ep_info); This function allows platforms to update ep_info for given image_id. The plat_bl1_common.c file provides default weak implementations of all above functions, the `bl1_plat_get_image_desc()` always return BL2 image descriptor, the `bl1_plat_get_next_image_id()` always return BL2 image ID and `bl1_plat_set_ep_info()` is empty and just returns. These functions gets compiled into all BL1 platforms by default. Platform setup in BL1, using `bl1_platform_setup()`, is now done _after_ the initialization of authentication module. This change provides the opportunity to use authentication while doing the platform setup in BL1. In order to store secure/non-secure context, BL31 uses percpu_data[] to store context pointer for each core. In case of BL1 only the primary CPU will be active hence percpu_data[] is not required to store the context pointer. This patch introduce bl1_cpu_context[] and bl1_cpu_context_ptr[] to store the context and context pointers respectively. It also also re-defines cm_get_context() and cm_set_context() for BL1 in bl1/bl1_context_mgmt.c. BL1 now follows the BL31 pattern of using SP_EL0 for the C runtime environment, to support resuming execution from a previously saved context. NOTE: THE `bl1_plat_set_bl2_ep_info()` PLATFORM PORTING FUNCTION IS NO LONGER CALLED BY BL1 COMMON CODE. PLATFORMS THAT OVERRIDE THIS FUNCTION MAY NEED TO IMPLEMENT `bl1_plat_set_ep_info()` INSTEAD TO MAINTAIN EXISTING BEHAVIOUR. Change-Id: Ieee4c124b951c2e9bc1c1013fa2073221195d881

FWU: Add Generic Firmware Update framework support in BL1 Firmware update(a.k.a FWU) feature is part of the TBB architecture. BL1 is responsible for carrying out the FWU process if platform specific code detects that it is needed. This patch adds support for FWU feature support in BL1 which is included by enabling `TRUSTED_BOARD_BOOT` compile time flag. This patch adds bl1_fwu.c which contains all the core operations of FWU, which are; SMC handler, image copy, authentication, execution and resumption. It also adds bl1.h introducing #defines for all BL1 SMCs. Following platform porting functions are introduced: int bl1_plat_mem_check(uintptr_t mem_base, unsigned int mem_size, unsigned int flags); This function can be used to add platform specific memory checks for the provided base/size for the given security state. The weak definition will invoke `assert()` and return -ENOMEM. __dead2 void bl1_plat_fwu_done(void *cookie, void *reserved); This function can be used to initiate platform specific procedure to mark completion of the FWU process. The weak definition waits forever calling `wfi()`. plat_bl1_common.c contains weak definitions for above functions. FWU process starts when platform detects it and return the image_id other than BL2_IMAGE_ID by using `bl1_plat_get_next_image_id()` in `bl1_main()`. NOTE: User MUST provide platform specific real definition for bl1_plat_mem_check() in order to use it for Firmware update. Change-Id: Ice189a0885d9722d9e1dd03f76cac1aceb0e25ed
