| * 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). |
