This is the follow-on patch to clean up the FSP support codes: - Remove the _t suffix on the structures defines - Use __packed for structure defines - Use U-Boot's assert() - Use standard bool true/false - Remove read_unaligned64() - Use memcmp() in the compare_guid() - Remove the cast in the memset() call - Replace some magic numbers with macros - Use panic() when no valid FSP image header is found - Change some FSP utility routines to use an fsp_ prefix - Add comment blocks for asm_continuation and fsp_init_done - Remove some casts in find_fsp_header() - Change HOB access macros to static inline routines - Add comments to mention find_fsp_header() may be called in a stackless environment - Add comments to mention init(¶ms) in fsp_init() cannot be removed Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
