2014-09-25cbfstool: Propogate compression errors back to the caller.Gabe Black
When compression fails for whatever reason, the caller should know about it rather than blindly assuming it worked correctly. That can prevent half compressed data from ending up in the image. This is currently happening for a segment of depthcharge which is triggering a failure in LZMA. The size of the "compressed" data is never set and is recorded as zero, and that segment effectively isn't loaded during boot.

2014-09-12cbfstool: Fix architecture check when adding payloadStefan Reinauer

2014-02-02Add section header parsing and use it in the mk-payload stepRonald G. Minnich
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.

2014-01-29cbfs: fix issues with word size and endianness.Ronald G. Minnich
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.

2013-02-05cbfstool: Add buffer management API.Hung-Te Lin
Many functions in cbfstool need to deal with a memory buffer - both location and size. Right now it's made by different ways: for ROM image using global variable (romsize, master_header); and in cbfs-* using return value for size and char** to return memory location. This may cause bugs like assuming incorrect return types, ex: uint32_t file_size = parse(); // which returns "-1" on error if (file_size <= 0) { ... And the parse error will never be caught. We can simplify this by introducing a buffer API, to change unsigned int do_something(char *input, size_t len, char **output, ...) into int do_something(struct buffer *input, struct buffer *output, ...) The buffer API will be used by further commits.

out a suitable address to put a XIP stage to. Specifically, you pass it the file (to get its filesize), its filename (as the header has a variable length that depends on it), and the granularity requirement it has to fit in (for XIP). The granularity is MTRR-style: when you request 0x10000, cbfstool looks for a suitable place in a 64kb-aligned 64kb block. cbfstool simply prints out a hex value which is the start address of a suitably located free memory block. That value can then be used with cbfs add-stage to store the file in the ROM image. It's a two-step operation (instead of being merged into cbfs add-stage) because the image must be linked twice: First, with some bogus, but safe base address (eg. 0) to figure out the target address (based on file size). Then a second time at the target address. The work flow is: - link file - cbfstool locate - link file again - cbfstool add-stage.

2009-09-14New cbfstool. Works without mmap or fork/exec andPatrick Georgi
supports fixed location files. Some parts are salvaged from the pre-commit version (esp. stage and payload creation), others are completely rewritten (eg. the main loop that handles file addition) Also adapt newconfig (we don't need cbfs/tools anymore) and fix some minor issues in the cbfstool-README.
