Subject: cmd_bootm.c: Make bootz handle BOOTM_STATE_FINDOTHER itself
X-Git-Tag: v2013.07-rc3~12
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=225fd8c5d4556547896a5d32ee092a258f3df638;p=oweals%2Fu-boot.git

cmd_bootm.c: Make bootz handle BOOTM_STATE_FINDOTHER itself

As a zImage does not have a U-Boot header, we cannot really do what
BOOTM_STATE_FINDOTHER does, exactly.  Break the ramdisk/fdt portions of
bootm_find_other into bootm_find_ramdisk/fdt which can be called in both
cases.
