[PATCH v3] Add sync to ensure flash_write_cmd is fully finished
Some CPUs like PPC, BLACKFIN need sync() to ensure cfi flash write command is fully finished. The sync() is defined in each CPU's io.h file. For those CPUs which do not need sync for now, a dummy sync() is defined in their io.h as well. Signed-off-by: Haiying Wang <Haiying.Wang@freescale.com>
