ARM platform changes for new version of image loading
This patch adds changes in ARM platform code to use new
version of image loading.
Following are the major changes:
-Refactor the signatures for bl31_early_platform_setup()
and arm_bl31_early_platform_setup() function to use
`void *` instead of `bl31_params_t *`.
-Introduce `plat_arm_bl2_handle_scp_bl2()` to handle
loading of SCP_BL2 image from BL2.
-Remove usage of reserve_mem() function from
`arm_bl1_early_platform_setup()`
-Extract BL32 & BL33 entrypoint info, from the link list
passed by BL2, in `arm_bl31_early_platform_setup()`
-Provides weak definitions for following platform functions:
plat_get_bl_image_load_info
plat_get_next_bl_params
plat_flush_next_bl_params
bl2_plat_handle_post_image_load
-Instantiates a descriptor array for ARM platforms
describing image and entrypoint information for
`SCP_BL2`, `BL31`, `BL32` and `BL33` images.
All the above changes are conditionally compiled using the
`LOAD_IMAGE_V2` flag.
