There are a handful of variants around CONFIG_SYS_USE_DATAFLASH and none of them now control anything further within their board config.h files, so remove these from CONFIG_SYS_EXTRA_OPTIONS and then remove the empty blocks in the board config.h files. In a few places further clean up related logic. Signed-off-by: Tom Rini <trini@konsulko.com>
