Usually these programs 123 * will install their own set of exception handlers, device 124 * drivers, set up the MMU, etc. - this means, that you cannot 125 * expect to re-enter U-Boot except by resetting the CPU. 126 * "RAMDisk Images" are more or less just data blocks, and their 127 * parameters (address, size) are passed to an OS kernel that is 128 * being started. 129 * "Multi-File Images" contain several images, typically an OS 130 * (Linux) kernel image and one or more data images like 131 * RAMDisks. This construct is useful for instance when you want 132 * to boot over the network using BOOTP etc., where the boot 133 * server provides just a single image file, but you want to get 134 * for instance an OS kernel and a RAMDisk image. 135 * 136 * "Multi-File Images" start with a list of image sizes, each 137 * image size (in bytes) specified by an "uint32_t" in network 138 * byte order. This list is terminated by an "(uint32_t)0". 139 * Immediately after the terminating 0 follow the images, one by 140 * one, all aligned on "uint32_t" boundaries (size rounded up to 141 * a multiple of 4 bytes - except for the last file). 142 * 143 * "Firmware Images" are binary images containing firmware (like 144 * U-Boot or FPGA images) which usually will be programmed to 145 * flash memory. 146 * 147 * "Script files" are command sequences that will be executed by 148 * U-Boot's command interpreter; this feature is especially 149 * useful when you configure U-Boot to use a real shell (hush) 150 * as command interpreter (=> Shell Scripts). 151 */ 152 153 #define IH_TYPE_INVALID 0 /* Invalid Image */ 154 #define IH_TYPE_STANDALONE 1 /* Standalone Program */ 155 #define IH_TYPE_KERNEL 2 /* OS Kernel Image */ 156 #define IH_TYPE_RAMDISK 3 /* RAMDisk Image */ 157 #define IH_TYPE_MULTI 4 /* Multi-File Image */ 158 #define IH_TYPE_FIRMWARE 5 /* Firmware Image */ 159 #define IH_TYPE_SCRIPT 6 /* Script file */ 160 #define IH_TYPE_FILESYSTEM 7 /* Filesystem Image (any type) */ 161 #define IH_TYPE_FLATDT 8 /* Binary Flat Device Tree Blob */ 162 #define IH_TYPE_KWBIMAGE 9 /* Kirkwood Boot Image */ 163 #define IH_TYPE_IMXIMAGE 10 /* Freescale IMXBoot Image */ 164 #define IH_TYPE_UBLIMAGE 11 /* Davinci UBL Image */ 165 #define IH_TYPE_OMAPIMAGE 12 /* TI OMAP Config Header Image */ 166 #define IH_TYPE_AISIMAGE 13 /* TI Davinci AIS Image */ 167 #define IH_TYPE_KERNEL_NOLOAD 14 /* OS Kernel Image, can run from any load address */ 168 #define IH_TYPE_PBLIMAGE 15 /* Freescale PBL Boot Image */ 169 170 /* 171 * Compression Types 172 */ 173 #define IH_COMP_NONE 0 /* No Compression Used */ 174 #define IH_COMP_GZIP 1 /* gzip Compression Used */ 175 #define IH_COMP_BZIP2 2 /* bzip2 Compression Used */ 176 #define IH_COMP_LZMA 3 /* lzma Compression Used */ 177 #define IH_COMP_LZO 4 /* lzo Compression Used */ 178 179 #define IH_MAGIC 0x27051956 /* Image Magic Number */ 180 #define IH_NMLEN 32 /* Image Name Length */ 181 182 /* Reused from common.h */ 183 #define ROUND(a, b) (((a) + (b) - 1) & ~((b) - 1)) 184 185 /* 186 * Legacy format image header, 187 * all data in network byte order (aka natural aka bigendian). 188 */ 189 typedef struct image_header { 190 __be32 ih_magic;
