2018-02-26ARM Platforms: Load HW_CONFIG in BL2Soby Mathew
The patch adds the necessary changes to load HW_CONFIG in BL2 for ARM Platforms : 1. The load address of HW_CONFIG is specified via the `hw_config_addr` property in TB_FW_CONFIG is loaded by BL1. The `hw_config_max_size` property defines the maximum size to be expected for the HW_CONFIG. The `arm_dyn_cfg_helpers.c` and corresponding header implements utility functions to parse these DT properties defined. The `arm_dyn_cfg.c` implements wrappers to these helpers to enable them to be invoked from ARM platform layer. 2. `HW_CONFIG` is added to the `bl2_mem_params_descs[]` array which is the list of images to be loaded by BL2. 3. The `libfdt` sources are now included when BL2 is built 4. A new helper `populate_next_bl_params_config()` is introduced in desc_image_load.c to populate the subsequent executable BL images with the `hw_config` and the corresponding `fw_config` if available. The `plat_get_next_bl_params()` API for ARM platforms is modified to invoke this new helper. 5. The implementation of `bl2_early_platform_setup2()` is modified to consider `arg0` as well in addition to `arg1` passed from BL1. 6. Bump up the BL2 size for Juno to accommodate the inclusion of libfdt. Change-Id: I80f1554adec41753e0d179a5237364f04fe13a3f Signed-off-by: Soby Mathew <soby.mathew@arm.com>

2016-09-20Add new version of image loading.Yatharth Kochar
This patch adds capability to load BL images based on image descriptors instead of hard coded way of loading BL images. This framework is designed such that it can be readily adapted by any BL stage that needs to load images. In order to provide the above capability the following new platform functions are introduced: bl_load_info_t *plat_get_bl_image_load_info(void); This function returns pointer to the list of images that the platform has populated to load. bl_params_t *plat_get_next_bl_params(void); This function returns a pointer to the shared memory that the platform has kept aside to pass trusted firmware related information that next BL image needs. void plat_flush_next_bl_params(void); This function flushes to main memory all the params that are passed to next image. int bl2_plat_handle_post_image_load(unsigned int image_id) This function can be used by the platforms to update/use image information for given `image_id`. `desc_image_load.c` contains utility functions which can be used by the platforms to generate, load and executable, image list based on the registered image descriptors. This patch also adds new version of `load_image/load_auth_image` functions in-order to achieve the above capability. Following are the changes for the new version as compared to old: - Refactor the signature and only keep image_id and image_info_t arguments. Removed image_base argument as it is already passed through image_info_t. Given that the BL image base addresses and limit/size are already provided by the platforms, the meminfo_t and entry_point_info arguments are not needed to provide/reserve the extent of free memory for the given BL image. - Added check for the image size against the defined max size. This is needed because the image size could come from an unauthenticated source (e.g. the FIP header). To make this check, new member is added to the image_info_t struct for identifying the image maximum size. New flag `LOAD_IMAGE_V2` is added in the Makefile. Default value is 0. NOTE: `TRUSTED_BOARD_BOOT` is currently not supported when `LOAD_IMAGE_V2` is enabled. Change-Id: Ia7b643f4817a170d5a2fbf479b9bc12e63112e79
