Subject: image: add magic number option for append-uImage-fakehdr
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f46a4a92934dc65ce6f1d68126f5e1664339d178;p=openwrt%2Fstaging%2Fansuel.git

image: add magic number option for append-uImage-fakehdr

'append-uImage-fakehdr' can now accept magic number as a second, optional
parameter (passed directly to 'mkimage' command with '-M' option). This
enables construction of proper Netgear-specific fake rootfs images
(required for flashing WNDR4300 for example).
