Usually these programs 119 * will install their own set of exception handlers, device 120 * drivers, set up the MMU, etc. - this means, that you cannot 121 * expect to re-enter U-Boot except by resetting the CPU. 122 * "RAMDisk Images" are more or less just data blocks, and their 123 * parameters (address, size) are passed to an OS kernel that is 124 * being started. 125 * "Multi-File Images" contain several images, typically an OS 126 * (Linux) kernel image and one or more data images like 127 * RAMDisks. This construct is useful for instance when you want 128 * to boot over the network using BOOTP etc., where the boot 129 * server provides just a single image file, but you want to get 130 * for instance an OS kernel and a RAMDisk image. 131 * 132 * "Multi-File Images" start with a list of image sizes, each 133 * image size (in bytes) specified by an "uint32_t" in network 134 * byte order. This list is terminated by an "(uint32_t)0". 135 * Immediately after the terminating 0 follow the images, one by 136 * one, all aligned on "uint32_t" boundaries (size rounded up to 137 * a multiple of 4 bytes - except for the last file). 138 * 139 * "Firmware Images" are binary images containing firmware (like 140 * U-Boot or FPGA images) which usually will be programmed to 141 * flash memory. 142 * 143 * "Script files" are command sequences that will be executed by 144 * U-Boot's command interpreter;
