create boot images for arm
Script and automate creation of boot images for armhf variant.
Raspberry Pi:
- basic scripts exist, they need to be fixed and committed to git
Wandboard, etc:
- fix linux-grsec, and other kernel aports to package also zImage + dtb files
- package u-boot, and build required boot loader variants
- improve setup-bootable to create arm bootables (likely need a switch to say witch bootloader to use)
