Plumb in the ability for U-Boot proper to accept an incoming standard passage from a previous phase, such as SPL or TF-A. This allows data to be passed from binary to binary when firmware is booting. Series-changes: 2 - Rebase to master - Rework global_data for new stdpass convention Series-changes: 3 - Move passage.h into this patch - Add passage_valid() to decide if stdpass was provided - Move arch_passage_entry() into this patch - Make the global_data fields present only when needed Signed-off-by: Simon Glass <sjg@chromium.org>
