Specify the FIT and include information about each loaded image, as required by the UPL handoff. Write the UPL handoff into the bloblist before jumping to the next phase. Control this using a runtime flag to avoid conflicting with other handoff mechanisms. Signed-off-by: Simon Glass <sjg@chromium.org> --- (no changes since v2) Changes in v2: - Hang when something goes wrong, to avoid a broken boot - Add a runtime flag to enable UPL - Put upl_image() calls in a common place boot/image-fit.c | 4 ++++ common/spl/spl.c | 8 ++++++++ common/spl/spl_fit.c | 9 +++++++++ include/asm-generic/global_data.h | 4 ++++ 4 files changed, 25 insertions(+)
