| 99 | * Image Types |
| 100 | * |
| 101 | * "Standalone Programs" are directly runnable in the environment |
| 102 | * provided by U-Boot; it is expected that (if they behave |
| 103 | * well) you can continue to work in U-Boot after return from |
| 104 | * the Standalone Program. |
| 105 | * "OS Kernel Images" are usually images of some Embedded OS which |
| 106 | * will take over control completely. Usually these programs |
| 107 | * will install their own set of exception handlers, device |
| 108 | * drivers, set up the MMU, etc. - this means, that you cannot |
| 109 | * expect to re-enter U-Boot except by resetting the CPU. |
| 110 | * "RAMDisk Images" are more or less just data blocks, and their |
| 111 | * parameters (address, size) are passed to an OS kernel that is |
| 112 | * being started. |
| 113 | * "Multi-File Images" contain several images, typically an OS |
| 114 | * (Linux) kernel image and one or more data images like |
| 115 | * RAMDisks. This construct is useful for instance when you want |
| 116 | * to boot over the network using BOOTP etc., where the boot |
| 117 | * server provides just a single image file, but you want to get |
| 118 | * for instance an OS kernel and a RAMDisk image. |
| 119 | * |
| 120 | * "Multi-File Images" start with a list of image sizes, each |
| 121 | * image size (in bytes) specified by an "uint32_t" in network |
| 122 | * byte order. This list is terminated by an "(uint32_t)0". |
| 123 | * Immediately after the terminating 0 follow the images, one by |
| 124 | * one, all aligned on "uint32_t" boundaries (size rounded up to |
| 125 | * a multiple of 4 bytes - except for the last file). |
| 126 | * |
| 127 | * "Firmware Images" are binary images containing firmware (like |
| 128 | * U-Boot or FPGA images) which usually will be programmed to |
| 129 | * flash memory. |
| 130 | * |
| 131 | * "Script files" are command sequences that will be executed by |
| 132 | * U-Boot's command interpreter; this feature is especially |
| 133 | * useful when you configure U-Boot to use a real shell (hush) |
| 134 | * as command interpreter (=> Shell Scripts). |
| 135 | * |
| 136 | * The following are exposed to uImage header. |
| 137 | * New IDs *MUST* be appended at the end of the list and *NEVER* |
| 138 | * inserted for backward compatibility. |
