2019-11-19util/chromeos: Indent code blocks instead of using ```Paul Menzel
This uses less lines, is the original Markdown syntax, and for short blocks better readable.

2019-09-30vboot: create board-specific test-only GBB HWID if not setHung-Te Lin
The HWID in vboot GBB is an identifier for machine model. On Chrome OS, that should be provisioned in manufacturing process (by collecting real hardware information), and will be checked in system startup. For bring up developers, they usually prefer to generate a test-only string for HWID. However that format was not well documented and cause problems. Further more, most Chromebooks are using HWID v3+ today while the test-only HWID is usually v2. Non-Chrome OS developers may also prefer their own format. To simplify development process, the GBB_CONFIG now defaults to empty string, and will be replaced by a board-specific test-only v2 HWID automatically. Developers can still override that in mainboard Kconfig if they prefer v3 or other arbitrary format. BUG=b:140067412 TEST=Built 'kukui' successfully. Removed kukui GBB config and built again, still seeing correct test HWID.

2019-09-30util/chromeos: revise description for more utility scripts in futureHung-Te Lin
The description.md and README.md was explicitly made for downloading or extracting some resources, but we need to add more Chrome OS related scripts soon; so the description should be revised. Also changed README.md for better markdown style, for example - Use #, ## to replace the old '-' headers - Use code format for file names - Use code block for example of shell execution Change-Id: Icc3677fa318b03f4aee1b0f5fb13b2095f2afe64 Signed-off-by: Hung-Te Lin <hungte@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/35664 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Georgi <pgeorgi@google.com>
2016-02-22util: Add scripts to download and extract blobsJoe Pillow
This turned out really handy when I tried to build coreboot for my Chromebox. These scripts can be used to extract System Agent reference code and other blobs (e.g. mrc.bin, refcode, VGA option roms) from a Chrome OS recovery image. crosfirmware.sh downloads a Chrome OS recovery image from the recovery image server, unpacks it, extracts the firmware update shell archive, extracts the firmware images from the shell archive. To download all Chrome OS firmware images, run $ ./crosfirmware.sh To download, e.g. the Panther firmware image, run $ ./crosfirmware.sh panther extract_blobs.sh extracts the blobs from a Chrome OS firmware image. Right now it will produce the ME firmware blob, IFD, VGA option rom, and mrc.bin Change-Id: I5fb7e14b10e03e18cd360bc35f1dc92e8ed34e63 Signed-off-by: Joe Pillow <joseph.a.pillow@gmail.com> Reviewed-on: https://review.coreboot.org/13752 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martinroth@google.com>
