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.

2013-02-01cbfstool: Make endian detection functions to work without prior setup.Hung-Te Lin
The 'host_bigendian' variable (and functions relying on it like ntohl/htonl) requires host detection by calling static which_endian() first -- which may be easily forgotten by developers. It's now a public function in common.c and doesn't need initialization anymore.

Add -v (verbose) to every command, and allow printing debug messages. Revise logging and debugging functions (fprintf(stderr,...), dprintf...) and verbose message printing with following macros: ERROR(xxx): E: xxx WARN(xxx) W: xxx LOG(xxx) xxx INFO(...) INFO: xxx (only when runs with -v ) DEBUG(...) DEBUG: xxx (only when runs with more than one -v) Example: cbfstool coreboot.rom print -v cbfstool coreboot.rom add -f file -n file -t raw -v -v Normal output (especially for parsing) should use printf, not any of these macros (see usage() and cbfs_locate(), cbfs_print_directory() for example).

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. Can we set it to 16 instead?

2012-11-08cbfstool: add offset parameter to create commandStefan Reinauer
CBFS allows coreboot rom images that are only partially covered by the filesystem itself. The intention of this feature was to allow EC / ME / IMC firmware to be inserted easily at the beginning of the image. However, this was never implemented in cbfstool. 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. Test: cbfstool coreboot.rom create 8192K bootblock.bin 64 0x700000 creates an 8M image that is 7M of 0xff and 1M of CBFS.

2009-11-09Add a "locate" function cbfstool, which helps you findPatrick Georgi
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.
