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). * * The following are exposed to uImage header. * New IDs *MUST* be appended at the end of the list and *NEVER* * inserted for backward compatibility. */ #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 */ #define IH_TYPE_KWBIMAGE 9 /* Kirkwood Boot Image */ #define IH_TYPE_IMXIMAGE 10 /* Freescale IMXBoot Image */ #define IH_TYPE_UBLIMAGE 11 /* Davinci UBL Image */ #define IH_TYPE_OMAPIMAGE 12 /* TI OMAP Config Header Image */ #define IH_TYPE_AISIMAGE 13 /* TI Davinci AIS Image */ /* OS Kernel Image, can run from any load address */ #define IH_TYPE_KERNEL_NOLOAD 14 #define IH_TYPE_PBLIMAGE 15 /* Freescale PBL Boot Image */ #define IH_TYPE_MXSIMAGE 16 /* Freescale MXSBoot Image */ #define IH_TYPE_GPIMAGE 17 /* TI Keystone GPHeader Image */ #define IH_TYPE_ATMELIMAGE 18 /* ATMEL ROM bootable Image */ #define IH_TYPE_SOCFPGAIMAGE 19 /* Altera SOCFPGA CV/AV Preloader */ #define IH_TYPE_X86_SETUP 20 /* x86 setup.bin Image */ #define IH_TYPE_LPC32XXIMAGE 21 /* x86 setup.bin Image */ #define IH_TYPE_LOADABLE 22 /* A list of typeless images */ #define IH_TYPE_RKIMAGE 23 /* Rockchip Boot Image */ #define IH_TYPE_RKSD 24 /* Rockchip SD card */ #define IH_TYPE_RKSPI 25 /* Rockchip SPI image */ #define IH_TYPE_ZYNQIMAGE 26 /* Xilinx Zynq Boot Image */ #define IH_TYPE_ZYNQMPIMAGE 27 /* Xilinx ZynqMP Boot Image */ #define IH_TYPE_ZYNQMPBIF 28 /* Xilinx ZynqMP Boot Image (bif) */ #define IH_TYPE_FPGA 29 /* FPGA Image */ #define IH_TYPE_VYBRIDIMAGE 30 /* VYBRID .vyb Image */ #define IH_TYPE_TEE 31 /* Trusted Execution Environment OS Image */ #define IH_TYPE_FIRMWARE_IVT 32 /* Firmware Image with HABv4 IVT */ #define IH_TYPE_PMMC 33 /* TI Power Management Micro-Controller Firmware */ #define IH_TYPE_STM32IMAGE 34 /* STMicroelectronics STM32 Image */ #define IH_TYPE_SOCFPGAIMAGE_V1 35 /* Altera SOCFPGA A10 Preloader */ #define IH_TYPE_MTKIMAGE 36 /* MediaTek BootROM loadable Image */ #define IH_TYPE_IMX8MIMAGE 37 /* Freescale IMX8MBoot Image */ #define IH_TYPE_IMX8IMAGE 38 /* Freescale IMX8Boot Image */ #define IH_TYPE_COPRO 39 /* Coprocessor Image for remoteproc*/ /* * Compression Types * * The following are exposed to uImage header. * New IDs *MUST* be appended at the end of the list and *NEVER* * inserted for backward compatibility. */ #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_COMP_LZMA 3 /* lzma Compression Used */ #define IH_COMP_LZO 4 /* lzo Compression Used */ #define IH_COMP_LZ4 5 /* lz4 Compression Used */ #define LZ4F_MAGIC 0x184D2204 /* LZ4 Magic Number */ #define IH_MAGIC 0x27051956 /* Image Magic Number */ #define IH_NMLEN 32 /* Image Name Length */ /* * Magic values specific to "openwrt,uimage" partitions */ #define IH_MAGIC_OKLI 0x4f4b4c49 /* 'OKLI' */ #endif /* __UIMAGE_H__ */
