Subject: arm: mvebu: Check that kwbimage blockid matches boot mode
X-Git-Tag: v2022.07~216^2~10
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f830703f4284a0e28e7060b85e659c619a0d8e23;p=platform%2Fkernel%2Fu-boot.git

arm: mvebu: Check that kwbimage blockid matches boot mode

Each boot mode has its own kwbimage specified by blockid. So check that
kwbimage is valid by blockid.
