Subject: ath79: move image check for devices with RedBoot
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=5897c52e78e3cd3846db083d48dd9d6b47ff3a08;p=openwrt%2Fstaging%2Fansuel.git

ath79: move image check for devices with RedBoot

Don't comence the switch to RAMFS when the image format is wrong. This
led to rebooting the device, which could lead to false impression that
upgrade succeded.
Being here, factor out the code responsible for upgrading RedBoot
devices to separate file.
