Aaron Durbin (adurbin(a)google.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/5087 -gerrit commit 1050d73a7ad6080329fdad9cf8787f796b5ccda9 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Thu Jan 30 17:19:46 2014 -0600 coreboot: infrastructure for different ramstage loaders There are 2 methods currently available in coreboot to load ramstage from romstage: cbfs and vboot. The vboot path had to be explicitly enabled and code needed to be added to each chipset to support both. Additionally, many of the paths were duplicated between the two. An additional complication is the presence of having a relocatable ramstage which creates another path with duplication. To rectify this situation provide a common API through the use of a callback to load the ramstage. The rest of the existing logic to handle all the various cases is put in a common place.

Patch set updated for coreboot: 9101cec x86: provide stage_exit() like arm
by Aaron Durbin Jan. 31, 2014

Jan. 31, 2014

Aaron Durbin (adurbin(a)google.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/5086 -gerrit commit 9101cecb3fc971083a457c63721c2b5fe9d592d3 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Thu Jan 30 15:48:29 2014 -0600 x86: provide stage_exit() like arm The arm architectures have a stage_exit() function which takes a void * pointer as an entry point. Provide the same API for x86. This can make the booting paths less architecture-specific.

Patch set updated for coreboot: d780f59 amd/cimx: fix sb(8|9)00 NULL type redefine

Jan. 31, 2014

Aaron Durbin (adurbin(a)google.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/5088 -gerrit commit d780f5905df20f1c0c336a90eae56b2ee5611818 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Thu Jan 30 22:20:01 2014 -0600 amd/cimx: fix sb(8|9)00 NULL type redefine It is inappropriate for chipset code to be redefining types -- especially NULL to a non-pointer type. There's only one non-straight forward change. A condition being checked was '!ptr_type == NULL' (0 as int). That check is actually 'ptr_type != NULL'.

Patch set updated for coreboot: c0d7d29 coreboot: infrastructure for different ramstage loaders
by Aaron Durbin Jan. 31, 2014

Jan. 31, 2014

Aaron Durbin (adurbin(a)google.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/5087 -gerrit commit c0d7d29e12674467212fca242da8de0b321920a2 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Thu Jan 30 17:19:46 2014 -0600 coreboot: infrastructure for different ramstage loaders There are 2 methods currently avaiable in coreboot to load ramstage from romstage: cbfs and vboot. The vboot path had to be explicitly enabled and code needed to be added to each chipset support both. Additionally, many of the paths were duplicated between the two. An additional complication is the presence of having a relocatable ramstage which creates another path with duplication. To rectify this situation provide a common API through the use of a callback to load the ramstage. The rest of the existing logic to handle all the various cases is put in a common place.

Patch merged into coreboot/master: d22d8cf baytrail: introduce pattrs
by gerrit＠coreboot.org Jan. 31, 2014

Jan. 31, 2014

the following patch was just integrated into master: commit d22d8cf5e792bd151f0e30d197f2c6a600a3c261 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Tue Sep 24 16:47:49 2013 -0500 baytrail: introduce pattrs The pattrs structure is intended for the supporting coreboot code to reference instead of going back to the source of the values (msrs, cpuid, etc). It essentially serves as a global structure for collecting attributes about the platform/processor. Additionally, the implementation provides a point during boot to hoook work before device enumeration/initialization by providing a init() function to soc_intel_baytrail_ops that is called before device work in the boot state machine. BUG=chrome-os-partner:22862 BUG=chrome-os-partner:22863 BRANCH=None TEST=Built and booted. Noted pattrs output.

This structure just sets the subsystem vendor and device id. Add a common one that all the other pci drivers can use for Bay Trail. BUG=chrome-os-partner:22860 BRANCH=None TEST=Built and booted while utilizing this new structure.

the following patch was just integrated into master: commit add056269d655226abc4a3ed5787bc31ba16d408 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Tue Sep 24 12:36:14 2013 -0500 baytrail: initialize graphics before MRC The graphics device needs to have its resource contraints initialized before running the reference code. Right now just use a 256MiB aperture, 32MiB of stolen memory data, and 2MiB GTT memory. BUG=chrome-os-partner:22869 BRANCH=None TEST=Built and booted. Noted amount of stolen memory matches configuration as well as BAR size within the graphics device.
