[PATCH] mtd/redboot: Handle holes in fis table

[PATCH] mtd/redboot: Handle holes in fis table

[Peter Korsgaard]

Hi,

Redboot simply sets the first character of a fis entry to 0xff on
"fis delete". The kernel redboot parser stops parsing on such an
entry, and without this patch any entries after a deleted image would
not be detected.
