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.

2013-12-09cbfstool: Properly handle EOF in update_fit stepAlexandru Gagniuc
During the update_fit step, 'file_length' is used to determine how many bytes are left in the CBFS file. It was decremented in a loop from an array 'mcus[num_mcus].size', but 'num_mcus' was incremented right before. Since 'mcus' is memset(0) externally, 'file_length' was never decremented. The loop exited when it reached a dummy terminator, usually 48 bytes of 0 which are internationally added to microcode blobs in coreboot. However, if that terminator is removed, the loop doesn't stop and continues until it segfaults.

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.

2013-02-01cbfstool: move flat-binary parsing to cbfs-mkpayload.Hung-Te Lin
The ELF parsing and payload building in add-flat-binary command should be isolated just like mkpayload and mkstage. Since the add-flat-binary command creates a payload in the end , move payload processing to cbfs-mkpayload.c. To test: cbfstool coreboot.rom add-flat-binary -f u-boot.bin -n fallback/payload \ -l 0x100000 -e 0x100020 To verify, get output from "cbfstool coreboot.rom print -v": fallback/payload 0x73ccc0 payload 124920 INFO: code (no compression, offset: 0x38, load: 0x1110000, length:..)

Currently "cbfstool locate" outputs a hex number without "0x" prefix. This makes extra step (prefix 0x, and then generate another temp file) in build process, and may be a problem when we want to allow changing its output format (ex, using decimal).

cbfstool.c uses lots of global variables for command line options and all named as "rom*". This may be confusing when other global variables also start with rom, ex: int size = rom_size + romsize; (rom_size is from command line and romsize is the size of last loaded ROM image).

2013-01-17armv7: Place reset vector + CBFS header + bootblock dynamicallyDavid Hendricks
This replaces hard-coded bootblock offsets using the new scheme. The assembler will place the initial branch instruction after BL1, skip 2 aligned chunks, and place the remaining bootblock code after. It will also leave an anchor string, currently 0xdeadbeef which cbfstool will find. Once found, cbfstool will place the master CBFS header at the next aligned offset. Here is how it looks: 0x0000 |--------------| | BL1 | 0x2000 |--------------| | branch | 0x2000 + align |--------------| | CBFS header | 0x2000 + align * 2 |--------------| | bootblock | |--------------| TODO: The option for alignment passed into cbfstool has always been 64.

This patch implements an additional parameter for cbfstool. If you call cbfstool like this: cbfstool coreboot.rom create 8192K bootblock.bin 64 0x700000 it will now create an 8M image with CBFS covering the last 1M of that image.
