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. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
