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) */ + +/* + * 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 */ + +#define IH_NAMEMAGIC 0x86680001 /* Name Magic Number */ +#define IH_SIZEMAX 5800000 /* Max image size */ +/* + * all data in network byte order (aka natural aka bigendian) + */ + +typedef struct image_header { + uint32_t ih_magic; /* Image Header Magic Number */ + uint32_t ih_hcrc; /* Image Header CRC Checksum */ + uint32_t ih_time; /* Image Creation Timestamp */ + uint32_t ih_size; /* Image Data Size */ + uint32_t ih_load; /* Data Load Address */ + uint32_t ih_ep; /* Entry Point Address */ + uint32_t ih_dcrc; /* Image Data CRC Checksum */ + uint8_t ih_os; /* Operating System */ + uint8_t ih_arch; /* CPU architecture */ + uint8_t ih_type; /* Image Type */ + uint8_t ih_comp; /* Compression Type */ +#ifdef NEW_IMAGE_HEADER + uint32_t ih_namemagic; /* image name CRC */ + uint8_t ih_name[IH_NMLEN-4]; /* image name */ +#else + uint8_t ih_name[IH_NMLEN]; /* Image Name */ +#endif +} image_header_t; + + +#endif /* __IMAGE_H__ */ diff --git a/target/linux/adm8668/image/lzma-loader/src/lzma.lds.in b/target/linux/adm8668/image/lzma-loader/src/lzma.lds.in new file mode 100644 index 000000000..d6c60ca0d --- /dev/null +++ b/target/linux/adm8668/image/lzma-loader/src/lzma.lds.in @@ -0,0 +1,24 @@ +OUTPUT_ARCH(mips) +ENTRY(entry) +SECTIONS +{ + /* Read-only sections, merged into text segment: */ + . = @LOADADDR@; + .text : + { + _ftext = . ; + *(.text.entry) + *(.text) + lzma_start = .; + kernel.o + lzma_end = .; + *(.rodata) + } =0 + + .reginfo : { *(.reginfo) } + + .bss : + { + *(.bss) + } +} diff --git a/target/linux/adm8668/image/lzma-loader/src/stubs.c b/target/linux/adm8668/image/lzma-loader/src/stubs.c new file mode 100644 index 000000000..468e5a1fd --- /dev/null +++ b/target/linux/adm8668/image/lzma-loader/src/stubs.c @@ -0,0 +1,52 @@ +#include <exports.h> + +#ifndef GCC_VERSION +#define GCC_VERSION (__GNUC__ * 1000 + __GNUC_MINOR__) +#endif /* GCC_VERSION */ + +/* + * k0 ($26) holds the pointer to the global_data; t9 ($25) is a call- + * clobbered register that is also used to set gp ($26).
