Fix the following issues with the console log output: * Make sure the welcome string is the first thing in the log output (during normal boot). * Prefix each message with the BL image name so it's clear which BL the output is coming from. * Ensure all output is wrapped in one of the log output macros so it can be easily compiled out if necessary. Change some of the INFO() messages to VERBOSE(), especially in the TSP. * Create some extra NOTICE() and INFO() messages during cold boot. * Remove all usage of \r in log output. Fixes ARM-software/tf-issues#231 Change-Id: Ib24f7acb36ce64bbba549f204b9cde2dbb46c8a3

Print out Trusted Firmware version at runtime at each BL stage. Message consists of TF version as defined statically in the Makefile (e.g. v0.4), build mode (debug|release) and a customizable build string: 1. By defining BUILD_STRING in command line when building TF 2. Default string is git commit ID 3. Empty if git meta-data is not available Fixes ARM-software/tf-issues#203 Change-Id: I5c5ba438f66ab68810427d76b49c5b9177a957d6

This patch implements a "tf_printf" which supports only the commonly used format specifiers in Trusted Firmware, which uses a lot less stack space than the stdlib printf function. Fixes ARM-software/tf-issues#116 Change-Id: I7dfa1944f4c1e634b3e2d571f49afe02d109a351

- Add support for loading a BL3-0 image in BL2. Information about memory extents is populated by platform-specific code. Subsequent handling of BL3-0 is also platform specific. The BL2 main function has been broken down to improve readability. The BL3-2 image is now loaded before the BL3-3 image to align with the boot flow. - Build system: Add support for specifying a BL3-0 image that will be included into the FIP image. - IO FIP driver: Add support for identifying a BL3-0 image inside a FIP image. - Update the documentation to reflect the above changes.

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 'attr' field of the meminfo data structure, which used to hold the bottom/top loading information, has been removed. Also the 'next' field has been removed as it wasn't used anywhere. The 'init_bl2_mem_layout()' function has been moved out of common code and put in BL1-specific code. It has also been renamed into 'bl1_init_bl2_mem_layout'. Fixes ARM-software/tf-issues#109 Change-Id: I3f54642ce7b763d5ee3b047ad0ab59eabbcf916d

bl2_main() was overwriting any platform set X1 parameter for BL3-1 with the value zero. This patch ensure that any platform set value is correctly passed to BL3-1. The FVP port adds a check to verify this parameter is being passed correctly. Fixes ARM-software/tf-issues#173 Change-Id: Ifbcda73d3d41d2b04a4baf5614e9d2d21f1717c8

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

Previously, platform.h contained many declarations and definitions used for different purposes. This file has been split so that: * Platform definitions used by common code that must be defined by the platform are now in platform_def.h. The exact include path is exported through $PLAT_INCLUDES in the platform makefile. * Platform definitions specific to the FVP platform are now in /plat/fvp/fvp_def.h. * Platform API declarations specific to the FVP platform are now in /plat/fvp/fvp_private.h. * The remaining platform API declarations that must be ported by each platform are still in platform.h but this file has been moved to /include/plat/common since this can be shared by all platforms.

The generic image loading and IO FIP code no longer forces the platform to create BL3-2 (Secure-EL1 Payload) specific definitions. The BL3-2 loading code in bl2/bl2main.c is wrapped by a #ifdef BL32_BASE blocks, allowing the BL3-2 definitions to be optional. Similarly for the name_uuid array defintion in drivers/io/io_fip.c. Also update the porting guide to reflect this change. The BL3-2 platform definitions remain non-configurably present in the FVP port.

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

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

This patch reworks the handover interface from: BL1 to BL2 and BL2 to BL3-1. It removes the raise_el(), change_el(), drop_el() and run_image() functions as they catered for code paths that were never exercised. BL1 calls bl1_run_bl2() to jump into BL2 instead of doing the same by calling run_image(). Similarly, BL2 issues the SMC to transfer execution to BL3-1 through BL1 directly. Only x0 and x1 are used to pass arguments to BL31. These arguments and parameters for running BL3-1 are passed through a reference to a 'el_change_info_t' structure. They were being passed value in general purpose registers earlier. Change-Id: Id4fd019a19a9595de063766d4a66295a2c9307e1

This patch introduces macros (SPSR_64 and SPSR_32) to create a SPSR for both aarch32 and aarch64 execution states. These macros allow the user to set fields in the SPSR depending upon its format. The make_spsr() function which did not allow manipulation of all the fields in the aarch32 SPSR has been replaced by these new macros. Change-Id: I9425dda0923e8d5f03d03ddb8fa0e28392c4c61e

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.

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

This patch adds support for loading a BL3-2 image in BL2. In case a BL3-2 image is found, it also passes information to BL3-1 about where it is located and the extents of memory available to it. Information about memory extents is populated by platform specific code. The documentation has also been updated to reflect the above changes.

This patch reworks BL2 to BL3-1 hand over interface by introducing a composite structure (bl31_args) that holds the superset of information that needs to be passed from BL2 to BL3-1. - The extents of secure memory available to BL3-1 - The extents of memory available to BL3-2 (not yet implemented) and BL3-3 - Information to execute BL3-2 (not yet implemented) and BL3-3 images This patch also introduces a new platform API (bl2_get_bl31_args_ptr) that needs to be implemented by the platform code to export reference to bl31_args structure which has been allocated in platform-defined memory. The platform will initialize the extents of memory available to BL3-3 during early platform setup in bl31_args structure. This obviates the need for bl2_get_ns_mem_layout platform API. BL2 calls the bl2_get_bl31_args_ptr function to get a reference to bl31_args structure. It uses the 'bl33_meminfo' field of this structure to load the BL3-3 image. It sets the entry point information for the BL3-3 image in the 'bl33_image_info' field of this structure. The reference to this structure is passed to the BL3-1 image. Also fixes issue ARM-software/tf-issues#25 Change-Id: Ic36426196dd5ebf89e60ff42643bed01b3500517

The Firmware Image Package (FIP) driver allows for data to be loaded from a FIP on platform storage. The FVP supports loading bootloader images from a FIP located in NOR FLASH. The implemented FVP policy states that bootloader images will be loaded from a FIP in NOR FLASH if available and fall back to loading individual images from semi-hosting. NOTE: - BL3-3(e.g. UEFI) is loaded into DRAM and needs to be configured to run from the BL33_BASE address. This is currently set to DRAM_BASE+128MB for the FVP.

This patch replaces the empty definition of display_boot_progress() in bl2_main.c with a weak definition. The former allowed bl2 to use the early_exceptions(). It is possible to do that with a simple weak definition as well. Change-Id: Idb3f425a5e265f3579b638e3d26bd8c9bb78f80d

Platform setup code has to reserve some memory for storing the memory layout information. It is populated in early platform setup code. blx_get_sec_mem_layout() functions used to return a copy of this structure. This patch modifies blx_get_sec_mem_layout() functions so that they now directly return a pointer to their memory layout structure. It ensures that the memory layout returned by blx_get_sec_mem_layout() is always up-to-date and also avoids a useless copy of the meminfo structure. Also rename blx_get_sec_mem_layout() to blx_plat_sec_mem_layout() to make it clear those functions are platform specific. Change-Id: Ic7a6f9d6b6236b14865ab48a9f5eff545ce56551
