+Subject: [PATCH 2/2] kexec-arm: add uImage support
+
+uImages are basically just zImages with a special header,
+we therefore just skip the header and let the normal zImage
+infrastructure do the actual work.

++ * Image Types
++ *
++ * "Standalone Programs" are directly runnable in the environment
++ *	provided by U-Boot; it is expected that (if they behave
++ *	well) you can continue to work in U-Boot after return from
++ *	the Standalone Program.
++ * "OS Kernel Images" are usually images of some Embedded OS which
++ *	will take over control completely. Usually these programs
++ *	will install their own set of exception handlers, device
++ *	drivers, set up the MMU, etc. - this means, that you cannot
++ *	expect to re-enter U-Boot except by resetting the CPU.
++ * "RAMDisk Images" are more or less just data blocks, and their
++ *	parameters (address, size) are passed to an OS kernel that is
++ *	being started.
++ * "Multi-File Images" contain several images, typically an OS
++ *	(Linux) kernel image and one or more data images like
++ *	RAMDisks. This construct is useful for instance when you want
++ *	to boot over the network using BOOTP etc., where the boot
++ *	server provides just a single image file, but you want to get
++ *	for instance an OS kernel and a RAMDisk image.
++ *
++ *	"Multi-File Images" start with a list of image sizes, each
++ *	image size (in bytes) specified by an "uint32_t" in network
++ *	byte order. This list is terminated by an "(uint32_t)0".
++ *	Immediately after the terminating 0 follow the images, one by
++ *	one, all aligned on "uint32_t" boundaries (size rounded up to
++ *	a multiple of 4 bytes - except for the last file).
++ *
++ * "Firmware Images" are binary images containing firmware (like
++ *	U-Boot or FPGA images) which usually will be programmed to
++ *	flash memory.
++ *
++ * "Script files" are command sequences that will be executed by
++ *	U-Boot's command interpreter; this feature is especially
++ *	useful when you configure U-Boot to use a real shell (hush)
++ *	as command interpreter (=> Shell Scripts).
