Tuomas Tynkkynen 6d176afe5e generic-extlinux-compatible: Add new bootloader for ARM
This module generates a /boot/extlinux/extlinux.conf bootloader
configuration file that is supported by e.g. U-Boot:

http://git.denx.de/?p=u-boot.git;a=blob;f=doc/README.distro;hb=refs/heads/master

With this, all ARM boards supported by U-Boot can be booted in a common
way (a single boot file generator, all boards booting via initrd like
x86) and with same boot menu functionality as GRUB has.

-- sample extlinux.conf file --
# Generated file, all changes will be lost on nixos-rebuild!

# Change this to e.g. nixos-42 to temporarily boot to an older configuration.
