X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4e1e18af653da81b07d3f12336925c82a07b0433;p=openwrt%2Fstaging%2Fsvanheule.git

bcm4908: build flashable & bootable firmware images

BCM4908 bootloader requires firmware with JFFS2 image containing:
1. cferam.000
2. 94908.dtb
3. vmlinux.lz
4. device custom files

cferam.000 can be obtained from the bcm63xx-cfe repository.
device custom files are stored in images dir.
