2016-02-10Kconfig: Move defaults for CBFS_SIZEMartin Roth
We want the question for CBFS size to be next to the rom size in the mainboard directory, but that doesn't seem to work for how people want to set the defaults. Instead of having the list of exceptions to the size, just set the defaults at the end of kconfig. - Move the defaults for chipsets not setting HAVE_INTEL_FIRMWARE into the chipset Kconfigs (gm45, nehalem, sandybridge, x4x) - Override the default for HAVE_INTEL_FIRMWARE on skylake. - Move the HAVE_INTEL_FIRMWARE default setting into the firmware Kconfig file - Move the location of the default CBFS_SIZE=ROM_SIZE to the end of the top level kconfig file, while leaving the question where it is. Test=rebuild Kconfig files before and after the change, verify that they are how they were intended to be. Note: the Skylake boards actually changed value, because they were picking up the 0x100000 from HAVE_INTEL_FIRMWARE instead of the 0x200000 desired. This was due to the SOC_INTEL_SKYLAKE being after the HAVE_INTEL_FIRMWARE default. Affected boards were: Google chell, glados, & lars and Intel kunimitsu.

2016-02-09Revert "northbridge/intel/peg: Disable unused ports"Nico Huber
This reverts commit 0e06f5bd70b45fd330d8dfb1dc77cce043caf841. It breaks gm45 and also does some magic without being asked too. It disables bridge devices permanently if no device was found on the se- condary bus. In a simple notebook world this might be ok, but it breaks hot-plugging and late detection (if a secondary bus device comes up too slow for the firmware to detect and the OS has to enumerate it).

2015-10-23Intel: Move MCRS ResourceTemplate outside of _CRS methodMartin Roth
On Broadwell, this reduces the number of 'remarks' in the IASL build from 222 to 3. Fixes these remarks: Object is not referenced (Name is within method [_CRS]) The ACPI compiler is trying to be helpful in letting us know that we're not using various fields in the MCRS ResourceTemplate when we define it inside of the _CRS method. Since we're not intending to use those objects in the method, it shouldn't be an issue, but the warning is annoying and can mask real issues. Moving the creation of the MCRS object to outside of the CRS method and referencing it from there solves this problem. This change was made for fsp_baytrail in commit 2eaa0d49 fsp_baytrail: Fix ACPI 'Object is not referenced' warnings Change-Id: I67a1faf963d1868f4133c7747a43a511cd28a44b Signed-off-by: Martin Roth <martinroth@google.com> Reviewed-on: http://review.coreboot.org/11268 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Alexandru Gagniuc <mr.nuke.me@gmail.com> Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

2015-06-23Kconfig: Move CBFS_SIZE into Mainboard menuMartin Roth
The CBFS size is really mainboard specific, since it really depends on size of the chip on the mainboard, so it makes sense to have it in the mainboard menu along with the ROM-chip size. - Move the CBFS_SIZE definition up in src/kconfig - Move the Mainboard Menu markers out of src/mainboard/kconfig into src/Kconfig so CBFS_SIZE can live in the mainboard menu. - Add a long list setting default values to do what the chipset directories were previously defaulting the values to. This will be trimmed down in a following patch that creates a common set of IFD routines. (Who knew that kconfig supported line wrapping?) - Update the help text.

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>

This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.
