From: Gabor Juhos Date: Fri, 24 Jan 2014 11:59:32 +0000 (+0000) Subject: ar71xx: image: fix size verification in the CatFiles macro X-Git-Tag: reboot~8089 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=4556632578f271ac283ca2caa7272c1eb6a04f68;p=oweals%2Fopenwrt.git ar71xx: image: fix size verification in the CatFiles macro The macro checks the size of the rootfs image even if the second parameter of the macro contains the size of an eraseblock. It is wrong because the size of the kernel image will be adjusted to the next eraseblock and the resulting image might be too large. Fix the macro to check the size of the final image instead of the rootfs image.
