2018-08-07ifdtool: fix flumap handling in chipsets prior ibex peak/5 seriesStefan Tauner
The Upper Map section in the descriptor contains a database of flash chips (VSCC Table). Its offset is located at a fixed offset from the beginning of the image. ifdtool falsely calculates the offset from the descriptor signature which has moved by 16 bytes with step b of the Ibex Peak (5 series) chipset. This produces bogus output for all chipsets older than that. This patch corrects the behavior by calculating the offset of flumap by adding 4096 - 256 - 4 to the start of the image.

2018-05-04ifdtool: Add a list of known platforms that support IFD_VERSION_2Furquan Shaikh
ifdtool has relied on one of the fields within FCBA(read_freq) to determine whether a platform supports IFD_VERSION_1 or IFD_VERSION_2. However, newer platforms like GLK and CNL do not have read_freq field in FCBA and so the value of these bits cannot be used as an indicator to distinguish IFD versions. In the long run, we need to re-write ifdtool to have a better mapping of SoC to IFD fields. But until that is done, this change adds a list of platforms that we know do not support read_freq field but still use IFD_VERSION_2. This change also updates GLK and CNL to pass in platform parameter to ifdtool.

2015-08-19ifdtool: Update to support Skylake+ descriptor formatDuncan Laurie
The descriptor format has changed with Skylake and some fields have moved or been expanded. This includes new SPI frequencies and chip densities, though unfortunately 30MHz in the new format conflicts with 50MHz in the old format... There are also new regions with a few reserved regions inserted before a new embedded controller region. Unfortunately there does not seem to be a documented version field so there does not seem to be an official way to determine if a specific descriptor is new or old. To work around this ifdtool checks the hardcoded "SPI Read Frequency" to see if it set for 20MHz (old descriptor) or 17MHz (new descriptor).

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>
