This construct is useful for instance when you want 168 * to boot over the network using BOOTP etc., where the boot 169 * server provides just a single image file, but you want to get 170 * for instance an OS kernel and a RAMDisk image. 171 * 172 * "Multi-File Images" start with a list of image sizes, each 173 * image size (in bytes) specified by an "uint32_t" in network 174 * byte order. This list is terminated by an "(uint32_t)0". 175 * Immediately after the terminating 0 follow the images, one by 176 * one, all aligned on "uint32_t" boundaries (size rounded up to 177 * a multiple of 4 bytes - except for the last file). 178 * 179 * "Firmware Images" are binary images containing firmware (like 180 * U-Boot or FPGA images) which usually will be programmed to 181 * flash memory. 182 * 183 * "Script files" are command sequences that will be executed by 184 * U-Boot's command interpreter;
