These APIs are used by platforms that need to decompress images. image_decompress_init(): This registers a temporary buffer and a decompressor callback. This should be called from platform init code. image_decompress_prepare(): This should be called before each compressed image is loaded. The best location to call this will be bl*_plat_handle_pre_image_load(). image_decompress(): This should be called after each compressed image is loaded. The best location to call this will be bl*_plat_handle_post_image_load(). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
