2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2015-09-17libpayload: allow compression at file header levelDaisuke Nojiri
Decompression is handled transparently within cbfs_get_file_content: const char *name = "foo.bmp"; void *dst = cbfs_get_file_content(media, name, type, NULL); To keep things consistent, a couple of API changes were necessary: - cbfs_get_file_content always returns a copy of the data, even for uncompressed files. It's the callers responsibility to free the memory. - same for cbfs_load_payload and cbfs_find_file. - cbfs_load_optionrom doesn't take a "dest" argument anymore but always returns a copy of the data, for compressed and uncompressed files. Like with cbfs_get_file_content, the caller is responsible to free it. It also decompresses based on extended file attributes instead of the cbfs_optionrom subheader that libpayload specified but that (AFAIK) nobody ever used, given that there's not even tooling for that.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

The calling convention of payload entry function is different by architecture. For example, X86 takes no arguments and ARM needs first param to be a cb_header_ptr*. To help payloads load and execute other payloads easily and correctly, we should provide the selfboot() function in libpayload, using same prototype as defined in coreboot environment.

2013-02-12libpayload: New CBFS to support multiple firmware media sources.Hung-Te Lin
Upgrade CBFS in libpayload to use new media-based implementation from coreboot ( http://review.coreboot.org/#/c/2182/ ). Old CBFS functions (cbfs_find, cbfs_find_file, get_cbfs_header) are still supported, although the recommended way is to use new CBFS API. To migrate your existing x86 payload source: - Change cbfs_find to cbfs_get_file - Change cbfs_find_file to cbfs_get_file_content - Prefix every CBFS call with a CBFS_DEFAULT_MEDIA argument. Ex, char *jpeg_data = cbfs_find_file("splash.jpg", CBFS_TYPE_BOOTSPLASH); => char *jpeg_data = cbfs_get_file_content( CBFS_DEFAULT_MEDIA, "splash.jpg", CBFS_TYPE_BOOTSPLASH); The legacy setup_cbfs_from_{ram,flash} is also supported, although the better equivalent is to make a new media instance: struct cbfs_media ram_media; init_cbfs_ram_media(&ram_media, start, size); char *data = cbfs_get_file_content(&ram_media, "myfile", my_type); Verified by being successfully linked with filo.
