When variable size SPL is used, the BL1 expects the SPL to be encapsulated differently: instead of putting the checksum at a fixed offset in the SPL blob, prepend the blob with a header including the size and the checksum. The enhancements include - adding a command line option, '--vs' to indicate the need for the variable size encapsulation - padding the fixed size encapsulated blob with 0xff instead of random memory contents - do not silently truncate the input file, report error instead - no need to explicitly closing files/freeing memory, this all happens on exit; removing cleanups it makes code clearer - profuse commenting - modify Makefile to allow enabling the new feature per board Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Signed-off-by: Rajeshwari S Shinde <rajeshwari.s@samsung.com> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
