Prevent a buffer overflow in mkimage when signing with SHA256
Due to the FIT_MAX_HASH_LEN constant not having been updated to support SHA256 signatures one will always see a buffer overflow in fit_image_process_hash when signing images that use this larger hash. This is exposed by vboot_test.sh. Signed-off-by: Michael van der Westhuizen <michael@smart-africa.com> Acked-by: Simon Glass <sjg@chromium.org> [trini: Rework a bit so move the exportable parts of hash.h outside of !USE_HOSTCC and only need that as a new include to image.h] Signed-off-by: Tom Rini <trini@ti.com>
