README for bootloader


	Das U-Boot (or just "U-Boot" for short) is Open Source Firmware for
	Embedded Power Architecture®, ARM, MIPS, x86 and other processors.

	CRUX-ARM uses U-Boot as default bootloader for some devices, like efikamx,
	cubieboard, cubieboard2, cubox, and maybe more in the future.

	In this repository you'll find all required to convert kernel images from
	zImage format to uImage, which used by U-Boot. To do that you need to use
	mkimage, which can be built with the Makefile provided.
	It's important to note that you must build mkimage with the compiler flags
	for your host.
	Also mkimage can convert files like initrd.gz to uInitrd in order to be
	loaded it by U-Boot at boot stage.

	To generate all the stuff required for a device you'll find a directory for
	each one. Take a look in "./devices/<yourdevice>" for more information.
