X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fheads%2Ftizen_8.0;p=platform%2Fkernel%2Fu-boot.git

tizen: bootscript: rpi4: Use recovery.img under backup partition

To prevent the broken recovery image, use recovery.img.64/32 under
backup partition. During TFM, it will be using for flashing.

If there is no backup file, original file will be used.
