Patch set updated for coreboot: b0b77d0 x86: add MIRROR_PAYLOAD_TO_RAM_BEFORE_LOADING option
by Aaron Durbin 27 Feb '14

27 Feb '14

Aaron Durbin (adurbin(a)google.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/5305 -gerrit commit b0b77d0f281b72d602cc264cae1da26713c3c455 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Tue Feb 25 20:36:56 2014 -0600 x86: add MIRROR_PAYLOAD_TO_RAM_BEFORE_LOADING option Boot speeds can be sped up by mirroring the payload into main memory before doing the actual loading. Systems that would benefit from this are typically Intel ones whose SPI are memory mapped. Without the SPI being cached all accesses to the payload in SPI while being loaded result in uncacheable accesses. Instead take advantage of the on-board SPI controller which has an internal cache and prefetcher by copying 64-byte cachelines using 32-bit word copies.

Patch merged into coreboot/master: 631312a baytrail: add support for disabling south cluster pci devices
by gerrit＠coreboot.org 27 Feb '14

27 Feb '14

the following patch was just integrated into master: commit 631312a2ea9256d793aa005a025eb7bf40bf1e27 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Tue Oct 29 16:37:10 2013 -0500 baytrail: add support for disabling south cluster pci devices When the southcluster pci devices are listed in the devicetree add the ability to perform the proper disabling sequence for turning off devices. This only turns off the pci device interface as well as put the device into D3Hot. It is not yet known how to put the TXE device into D3Hot so it's currently not possible to disable that device. Also, expose the southcluster_enable_dev() function so that other devices can call this if they require doing specific things before disabling the device. The southcluster_enable_dev() is only called on devices found in the devicetree and if they currently have no ops associated with them. BUG=chrome-os-partner:22871 BRANCH=None TEST=Built and booted through depthcharge. Interrogated output to ensure devices were being properly disabled.
