* cdl/redboot.cdl (CYGBLD_REDBOOT_MIN_IMAGE_SIZE): Correct the description to match what the option is actually used for. * src/flash.c (find_free, fis_free, fis_find_free): Don't ignore an extra CYGBLD_REDBOOT_MIN_IMAGE_SIZE amount from the start. This fixes the case where nothing uses the start of flash.
