This includes the following fixes: - Define needed __init_end symbol - see initr_reloc_global_data() - Drop SH-specific struct bd_info - Add an empty relocate_code() function This prevents build errors with generic board, but the code will still need work. Perhaps this is a better alternative than deleting the code. Signed-off-by: Simon Glass <sjg@chromium.org>
