From cab0b5b0452556c9f7ba3fa98c233d3a6a62b023 Mon Sep 17 00:00:00 2001 From: Soby Mathew Date: Mon, 15 Jan 2018 14:45:33 +0000 Subject: [PATCH] ARM Platforms: Load HW_CONFIG in BL2 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.
