[PATCH V2] bcm4908: build flashable & bootable firmware images

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

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. It requires
specifying directory path that is defined using COMPATIBLE variable.

For convenience directories with device custom files are named the same
way.
