In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.
This reverts commit 99a0949b72.

|
|
* 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).
