README for uboot

	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, wm8505, 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 related.
