Huge patch boils down massive kernel image parsing and boot action to a modest sequence of code that actually boots the kernel. Signed-off-by: Andy Green <andy@openmoko.com>

/*
|
||||
* 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).
