Subject: uboot-mediatek: bpi-r3: prepare for larger FIT structures
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3c2f7bb555c2cd5c4be8aed11b9d31b48cc0bcf8;p=openwrt%2Fstaging%2Fnbd.git

uboot-mediatek: bpi-r3: prepare for larger FIT structures

Instead of reading only a single 4kiB page, read the first 128kiB to
determine the size of an uImage.FIT using 'imsz' or 'imszb'.
This will be needed once we add more Device Tree Overlays, which may
happen for the BPi-R3 mini.
