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; this feature is especially 145 * useful when you configure U-Boot to use a real shell (hush) 146 * as command interpreter (=> Shell Scripts). 147 */ 148 149 #define IH_TYPE_INVALID 0 /* Invalid Image */ 150 #define IH_TYPE_STANDALONE 1 /* Standalone Program */ 151 #define IH_TYPE_KERNEL 2 /* OS Kernel Image */ 152 #define IH_TYPE_RAMDISK 3 /* RAMDisk Image */ 153 #define IH_TYPE_MULTI 4 /* Multi-File Image */ 154 #define IH_TYPE_FIRMWARE 5 /* Firmware Image */ 155 #define IH_TYPE_SCRIPT 6 /* Script file */ 156 #define IH_TYPE_FILESYSTEM 7 /* Filesystem Image (any type) */ 157 #define IH_TYPE_FLATDT 8 /* Binary Flat Device Tree Blob */ 158 #define IH_TYPE_KWBIMAGE 9 /* Kirkwood Boot Image */ 159 160 /* 161 * Compression Types 162 */ 163 #define IH_COMP_NONE 0 /* No Compression Used */ 164 #define IH_COMP_GZIP 1 /* gzip Compression Used */ 165 #define IH_COMP_BZIP2 2 /* bzip2 Compression Used */ 166 #define IH_COMP_LZMA 3 /* lzma Compression Used */ 167 #define IH_COMP_LZO 4 /* lzo Compression Used */ 168 169 #define IH_MAGIC 0x27051956 /* Image Magic Number */ 170 #define IH_NMLEN 32 /* Image Name Length */ 171 172 /* 173 * Legacy format image header, 174 * all data in network byte order (aka natural aka bigendian). 175 */ 176 typedef struct image_header { 177 uint32_t ih_magic;
