Usually these programs 209 * will install their own set of exception handlers, device 210 * drivers, set up the MMU, etc. - this means, that you cannot 211 * expect to re-enter U-Boot except by resetting the CPU. 212 * "RAMDisk Images" are more or less just data blocks, and their 213 * parameters (address, size) are passed to an OS kernel that is 214 * being started. 215 * "Multi-File Images" contain several images, typically an OS 216 * (Linux) kernel image and one or more data images like 217 * RAMDisks. This construct is useful for instance when you want 218 * to boot over the network using BOOTP etc., where the boot 219 * server provides just a single image file, but you want to get 220 * for instance an OS kernel and a RAMDisk image. 221 * 222 * "Multi-File Images" start with a list of image sizes, each 223 * image size (in bytes) specified by an "uint32_t" in network 224 * byte order. This list is terminated by an "(uint32_t)0". 225 * Immediately after the terminating 0 follow the images, one by 226 * one, all aligned on "uint32_t" boundaries (size rounded up to 227 * a multiple of 4 bytes - except for the last file). 228 * 229 * "Firmware Images" are binary images containing firmware (like 230 * U-Boot or FPGA images) which usually will be programmed to 231 * flash memory. 232 * 233 * "Script files" are command sequences that will be executed by 234 * U-Boot's command interpreter;
