This construct is useful for instance when you want 195 * to boot over the network using BOOTP etc., where the boot 196 * server provides just a single image file, but you want to get 197 * for instance an OS kernel and a RAMDisk image. 198 * 199 * "Multi-File Images" start with a list of image sizes, each 200 * image size (in bytes) specified by an "uint32_t" in network 201 * byte order. This list is terminated by an "(uint32_t)0". 202 * Immediately after the terminating 0 follow the images, one by 203 * one, all aligned on "uint32_t" boundaries (size rounded up to 204 * a multiple of 4 bytes - except for the last file). 205 * 206 * "Firmware Images" are binary images containing firmware (like 207 * U-Boot or FPGA images) which usually will be programmed to 208 * flash memory. 209 * 210 * "Script files" are command sequences that will be executed by 211 * U-Boot's command interpreter;
