Usually these programs 128 * will install their own set of exception handlers, device 129 * drivers, set up the MMU, etc. - this means, that you cannot 130 * expect to re-enter U-Boot except by resetting the CPU. 131 * "RAMDisk Images" are more or less just data blocks, and their 132 * parameters (address, size) are passed to an OS kernel that is 133 * being started. 134 * "Multi-File Images" contain several images, typically an OS 135 * (Linux) kernel image and one or more data images like 136 * RAMDisks. This construct is useful for instance when you want 137 * to boot over the network using BOOTP etc., where the boot 138 * server provides just a single image file, but you want to get 139 * for instance an OS kernel and a RAMDisk image. 140 * 141 * "Multi-File Images" start with a list of image sizes, each 142 * image size (in bytes) specified by an "uint32_t" in network 143 * byte order. This list is terminated by an "(uint32_t)0". 144 * Immediately after the terminating 0 follow the images, one by 145 * one, all aligned on "uint32_t" boundaries (size rounded up to 146 * a multiple of 4 bytes - except for the last file). 147 * 148 * "Firmware Images" are binary images containing firmware (like 149 * U-Boot or FPGA images) which usually will be programmed to 150 * flash memory. 151 * 152 * "Script files" are command sequences that will be executed by 153 * U-Boot's command interpreter; this feature is especially 154 * useful when you configure U-Boot to use a real shell (hush) 155 * as command interpreter (=> Shell Scripts). 156 */ 157 158 #define IH_TYPE_INVALID 0 /* Invalid Image */ 159 #define IH_TYPE_STANDALONE 1 /* Standalone Program */ 160 #define IH_TYPE_KERNEL 2 /* OS Kernel Image */ 161 #define IH_TYPE_RAMDISK 3 /* RAMDisk Image */ 162 #define IH_TYPE_MULTI 4 /* Multi-File Image */ 163 #define IH_TYPE_FIRMWARE 5 /* Firmware Image */ 164 #define IH_TYPE_SCRIPT 6 /* Script file */ 165 #define IH_TYPE_FILESYSTEM 7 /* Filesystem Image (any type) */ 166 #define IH_TYPE_FLATDT 8 /* Binary Flat Device Tree Blob */ 167 #define IH_TYPE_KWBIMAGE 9 /* Kirkwood Boot Image */ 168 #define IH_TYPE_IMXIMAGE 10 /* Freescale IMXBoot Image */ 169 #define IH_TYPE_UBLIMAGE 11 /* Davinci UBL Image */ 170 #define IH_TYPE_OMAPIMAGE 12 /* TI OMAP Config Header Image */ 171 #define IH_TYPE_AISIMAGE 13 /* TI Davinci AIS Image */ 172 #define IH_TYPE_KERNEL_NOLOAD 14 /* OS Kernel Image, can run from any load address */ 173 #define IH_TYPE_PBLIMAGE 15 /* Freescale PBL Boot Image */ 174 175 /* 176 * Compression Types 177 */ 178 #define IH_COMP_NONE 0 /* No Compression Used */ 179 #define IH_COMP_GZIP 1 /* gzip Compression Used */ 180 #define IH_COMP_BZIP2 2 /* bzip2 Compression Used */ 181 #define IH_COMP_LZMA 3 /* lzma Compression Used */ 182 #define IH_COMP_LZO 4 /* lzo Compression Used */ 183 184 #define IH_MAGIC 0x27051956 /* Image Magic Number */ 185 #define IH_NMLEN 32 /* Image Name Length */ 186 187 /* Reused from common.h */ 188 #define ROUND(a, b) (((a) + (b) - 1) & ~((b) - 1)) 189 190 /* 191 * Legacy format image header, 192 * all data in network byte order (aka natural aka bigendian). 193 */ 194 typedef struct image_header { 195 __be32 ih_magic;
