the following patch was just integrated into master: commit 48b4cbdd94f1e126314eb055cd387011e7875845 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Thu Sep 1 17:46:41 2016 -0500 mainboard/google/reef: remove unused gpio.h macros Some of the macros in gpio.h are no longer used because devicetree.cb is being used to autogeneric the ACPI AML. Therefore remove the unused macros.

Patch set updated for coreboot: gm45/gma.c: clean up some registers
by Arthur Heymans 03 Sep '16

03 Sep '16

Arthur Heymans (arthur(a)aheymans.xyz) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/16217 -gerrit commit 8c99ab26438b74fbf46501335b618634878525be Author: Arthur Heymans <arthur(a)aheymans.xyz> Date: Mon Aug 15 00:04:34 2016 +0200 gm45/gma.c: clean up some registers According to "G45: Volume 3: Display Register Intel ® 965G Express Chipset Family and Intel ® G35 Express Chipset Graphics Controller" some registries are set incorrectly in gm45/gma.c. Some values are changed after comparing them with the values the i915 linux kernel (3.13 was used) module sets while modesetting. The values were obtained using 'intel_reg' from intel-gpu-tools, during a normal boot and with 'nomodeset' as a kernel argument. Some registers that don't exist on gm45 are set in gma.c, which is probably the result of copying code from a more recent intel northbridge. The result is that that gm45 laptops with wxga displays still work as before. gm45 laptops with wxga+ or higher resolution now just work, where previously a black screen was shown. TEST: build with native graphic init and flash on a gm45 target, like lenovo x200.

Patch set updated for coreboot: gm45/gma.c: use screen on vga connector if connected
by Arthur Heymans 03 Sep '16

03 Sep '16

Arthur Heymans (arthur(a)aheymans.xyz) just uploaded a new patch set to gerrit, which you can find at https://review.coreboot.org/16295 -gerrit commit 51dc727c71bbb10519a670b83b67a84f704e003a Author: Arthur Heymans <arthur(a)aheymans.xyz> Date: Mon Aug 22 17:58:46 2016 +0200 gm45/gma.c: use screen on vga connector if connected The intel x4x and gm45 have very similar integrated graphic devices. Currently the x4x native graphic init enables VGA, while gm45 can output on LVDS. This patch reuses the x4x graphic initialisation code to enable output on VGA in gm45 in a way that the behavior is similar to vbios: If no VGA display is connected the internal LVDS screen is used. If an external screen is detected on the VGA port it will be used instead.
