We are introducing a new generic relocation features and we want this to be the default. So we need to opt all architectures out first. Some may never have relocation, but those that do will eventually move over to this generic relocation framework.
This is part of the unified board effort, but since we are only dealing with relocation in this series, CONFIG_SYS_SKIP_RELOC is more appropriate than CONFIG_SYS_LEGACY_BOARD.
Signed-off-by: Simon Glass sjg@chromium.org --- Changes in v2: - Use CONFIG_SYS_SKIP_RELOC instead of CONFIG_SYS_LEGACY_BOARD
