Patch set updated for coreboot: 51eb0fc cbfs: add new API and boot_device support
by Aaron Durbin 08 Apr '15

08 Apr '15

Aaron Durbin (adurbin(a)google.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/9134 -gerrit commit 51eb0fc61219c6580f1e985cc0932c6411a47f45 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Fri Mar 27 00:23:49 2015 -0500 cbfs: add new API and boot_device support A new CBFS API is introduced to allow making CBFS access easier for providing multiple CBFS sources. That is achieved by decoupling the cbfs source from a CBFS file. A CBFS source is described by a descriptor. It contains the necessary properties for walking a CBFS to locate a file. The CBFS file is then decoupled from the CBFS descriptor in that it's no longer needed to access the contents of the file. All of this is accomplished using the regions infrastructure by repsenting CBFS sources and files as region_devices. Because region_devices can be chained together forming subregions this allows one to decouple a CBFS source from a file. This also allows one to provide CBFS files that came from other sources for payload and/or stage loading. The last concept this change introduces is the boot device. The boot device is represented as a region_device that covers the entire media where the main CBFS is located. Using the boot media allows one to access the media through the region_device operations that don't fall within the CBFS proper. Previously, struct cbfs_media was being used for accessing content outside of the boot CBFS proper. Note: this change purposefully ignores the chromeos code.

Patch merged into coreboot/master: e5e3630 timer: Add generic udelay() implementation
by gerrit＠coreboot.org 08 Apr '15

08 Apr '15

the following patch was just integrated into master: commit e5e36306a9a5bf96ab8cc990d93bbd62030e635f Author: Aaron Durbin <adurbin(a)chromium.org> Date: Thu Sep 25 10:05:15 2014 -0500 timer: Add generic udelay() implementation Add GENERIC_UDELAY Kconfig option so that a generic udelay() implementation is provided utilizing the monotonic timer. That way each board/chipset doesn't need to duplicate the same udelay(). Additionally, assume that GENERIC_UDELAY implies init_timer() is not required. BUG=None BRANCH=None TEST=Built nyan, ryu, and rambi. May need help testing.
