Usually these programs * will install their own set of exception handlers, device * drivers, set up the MMU, etc. - this means, that you cannot * expect to re-enter U-Boot except by resetting the CPU. * "RAMDisk Images" are more or less just data blocks, and their * parameters (address, size) are passed to an OS kernel that is * being started. * "Multi-File Images" contain several images, typically an OS * (Linux) kernel image and one or more data images like * RAMDisks. This construct is useful for instance when you want * to boot over the network using BOOTP etc., where the boot * server provides just a single image file, but you want to get * for instance an OS kernel and a RAMDisk image. * * "Multi-File Images" start with a list of image sizes, each * image size (in bytes) specified by an "uint32_t" in network * byte order. This list is terminated by an "(uint32_t)0". * Immediately after the terminating 0 follow the images, one by * one, all aligned on "uint32_t" boundaries (size rounded up to * a multiple of 4 bytes - except for the last file). * * "Firmware Images" are binary images containing firmware (like * U-Boot or FPGA images) which usually will be programmed to * flash memory. * * "Script files" are command sequences that will be executed by * U-Boot's command interpreter; this feature is especially * useful when you configure U-Boot to use a real shell (hush) * as command interpreter (=> Shell Scripts). */ #define IH_TYPE_INVALID 0 /* Invalid Image */ #define IH_TYPE_STANDALONE 1 /* Standalone Program */ #define IH_TYPE_KERNEL 2 /* OS Kernel Image */ #define IH_TYPE_RAMDISK 3 /* RAMDisk Image */ #define IH_TYPE_MULTI 4 /* Multi-File Image */ #define IH_TYPE_FIRMWARE 5 /* Firmware Image */ #define IH_TYPE_SCRIPT 6 /* Script file */ #define IH_TYPE_FILESYSTEM 7 /* Filesystem Image (any type) */ #define IH_TYPE_FLATDT 8 /* Binary Flat Device Tree Blob */ /* * Compression Types */ #define IH_COMP_NONE 0 /* No Compression Used */ #define IH_COMP_GZIP 1 /* gzip Compression Used */ #define IH_COMP_BZIP2 2 /* bzip2 Compression Used */ #define IH_MAGIC 0x27051956 /* Image Magic Number */ #define IH_NMLEN 32 /* Image Name Length */ /* * Legacy format image header, * all data in network byte order (aka natural aka bigendian). */ typedef struct image_header { uint32_t ih_magic;
