cbfstool: Add cbfs_image new CBFS image manipulation API. Current cbfstool implementation is relying on global variables to pass processed data, and the calculation of address is based on x86 architecture (ex, always assuming 0x0000 as invalid address), not easy to be used on platforms without top-aligned memory mapping. This CL is a first step to start a new cbfstool without global variables, and to prevent assuming memory layout in x86 mode. The first published APIs are for reading and writing existing CBFS ROM image files (and to find file entries in a ROM file). Read cbfs_image.h for detail usage of each API function.

Add section header parsing and use it in the mk-payload step This completes the improvements to the ELF file parsing code. We can now parse section headers too, across all 4 combinations of word size and endianness. I had hoped to completely remove the use of htonl until I found it in cbfs_image.c. That's a battle for another day. There's now a handy macro to create magic numbers in host byte order. I'm using it for all the PAYLOAD_SEGMENT_* constants and maybe we can use it for the others too, but this is sensitive code and I'd rather change one thing at a time. To maximize the ease of use for users, elf parsing is accomplished with just one function: int elf_headers(const struct buffer *pinput, Elf64_Ehdr *ehdr, Elf64_Phdr **pphdr, Elf64_Shdr **pshdr) which requires the ehdr and pphdr pointers to be non-NULL, but allows the pshdr to be NULL. If pshdr is NULL, the code will not try to read in section headers. To satisfy our powerful scripts, I had to remove the ^M from an unrelated microcode file. BUG=None TEST=Build a peppy image (known to boot) with old and new versions and verify they are bit-for-bit the same. This was also fully tested across all chromebooks for building and booting and running chromeos. BRANCH=None Change-Id: I54dad887d922428b6175fdb6a9cdfadd8a6bb889 Signed-off-by: Ronald G.

cbfs: fix issues with word size and endianness. Add XDR functions and use them to convert the ELF headers to native headers, using the Elf64 structs to ensure we accomodate all word sizes. Also, use these XDR functions for output. This may seem overly complex but it turned out to be much the easiest way to do this. Note that the basic elf parsing function in cbfs-mkstage.c now works over all ELF files, for all architectures, endian, and word size combinations. At the same time, the basic elf parsing in cbfs-mkstage.c is a loop that has no architecture-specific conditionals. Add -g to the LDFLAGS while we're here. It's on the CFLAGS so there is no harm done. This code has been tested on all chromebooks that use coreboot to date. I added most of the extra checks from ChromeOS and they triggered a lot of warnings, hence the other changes. I had to take -Wshadow back out due to the many errors it triggers in LZMA.

cbfs: fix issues with word size and endianness. Add XDR functions and use them to convert the ELF headers to native headers, using the Elf64 structs to ensure we accomodate all word sizes. Also, use these XDR functions for output. This may seem overly complex but it turned out to be much the easiest way to do this. Note that the basic elf parsing function in cbfs-mkstage.c now works over all ELF files, for all architectures, endian, and word size combinations. At the same time, the basic elf parsing in cbfs-mkstage.c is a loop that has no architecture-specific conditionals. Add -g to the LDFLAGS while we're here. It's on the CFLAGS so there is no harm done. This code has been tested on all chromebooks that use coreboot to date. I added most of the extra checks from ChromeOS and they triggered a lot of warnings, hence the other changes. I had to take -Wshadow back out due to the many errors it triggers in LZMA. BUG=None TEST=Build and boot for Peppy; works fine. Build and boot for nyan, works fine. Build for qemu targets and armv8 targets.

cbfs: fix issues with word size and endianness. Add XDR functions and use them to convert the ELF headers to native headers, using the Elf64 structs to ensure we accomodate all word sizes. Also, use these XDR functions for output. This may seem overly complex but it turned out to be much the easiest way to do this. Note that the basic elf parsing function in cbfs-mkstage.c now works over all ELF files, for all architectures, endian, and word size combinations. At the same time, the basic elf parsing in cbfs-mkstage.c is a loop that has no architecture-specific conditionals. Add -g to the LDFLAGS while we're here. It's on the CFLAGS so there is no harm done. This code has been tested on all chromebooks that use coreboot to date. I added most of the extra checks from ChromeOS and they triggered a lot of warnings, hence the other changes. I had to take -Wshadow back out due to the many errors it triggers in LZMA.

cbfstool: Add cbfs_image new CBFS image manipulation API. Current cbfstool implementation is relying on global variables to pass processed data, and the calculation of address is based on x86 architecture (ex, always assuming 0x0000 as invalid address), not easy to be used on platforms without top-aligned memory mapping. This CL is a first step to start a new cbfstool without global variables, and to prevent assuming memory layout in x86 mode. The first published APIs are for reading and writing existing CBFS ROM image files (and to find file entries in a ROM file). Read cbfs_image.h for detail usage of each API function.

cbfstool: Fix crash on image without bootblock in end of ROM. On platforms with CBFS data filling end of ROM image without bootblock in the end (ex, ARM), calculation of "next valid entry" may exceed ROM image buffer in memory and raise segmentation fault when we try to compare its magic value. To fix this, always check if the entry address is inside ROM image buffer. Verified to build and boot successfully on qemu/x86 and armv7/snow.
