the following patch was just integrated into master: commit e1213d16f38c7950b2c70dfccccbb8d9c08a0ee9 Author: Kyösti Mälkki <kyosti.malkki(a)gmail.com> Date: Tue May 26 18:43:02 2015 +0300 pcengines/apu1: Enable HAVE_ACPI_RESUME Note: apu1c models do not support this. That we expose S3 in ACPI table while it is not available, is a wider issue to solve.

Patch set updated for coreboot: 9b70edb vboot: use only offsets for tracking firmware components

Aaron Durbin (adurbin(a)chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10221 -gerrit commit 9b70edb630b522029d1748ed084eb3a8793a2a95 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Fri May 15 15:57:51 2015 -0500 vboot: use only offsets for tracking firmware components Because of the fmap API returning pointers to represent regions within the boot device a vboot_region structure was used to track the case where offsets could be pointers on x86 but not on !x86. Normalize this tracking to use offsets only as it provides consistency in the code.

Patch set updated for coreboot: 6b8aa15 coreboot: introduce boot_device
by Aaron Durbin 26 May '15

26 May '15

Aaron Durbin (adurbin(a)chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10216 -gerrit commit 6b8aa156df857032706c4730491444f152a4ded0 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Fri May 15 13:15:34 2015 -0500 coreboot: introduce boot_device The boot_device is a region_device that represents the device from which coreboot retrieves and boots its stages. The existing cbfs implementations use the boot_device as the intermediary for accessing the CBFS region. Also, there's currently only support for a read-only view of the boot_device. i.e. one cannot write to the boot_device using this view. However, a writable boot_device could be added in the future.

Patch set updated for coreboot: 4b98d0f assets: abstract away the firmware assets used for booting
by Aaron Durbin 26 May '15

26 May '15

Aaron Durbin (adurbin(a)chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10264 -gerrit commit 4b98d0f3e48d015169d2e5527c7ea60927ef5e6c Author: Aaron Durbin <adurbin(a)chromium.org> Date: Wed May 20 12:08:55 2015 -0500 assets: abstract away the firmware assets used for booting As there can be more than one source of firmware assets this patch generalizes the notion of locating a particular asset. struct asset is added along with some helper functions for working on assets as a first class citizen.

Patch set updated for coreboot: 9f0f0df fmap: new API using region_device

Aaron Durbin (adurbin(a)chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/9170 -gerrit commit 9f0f0df514327527577188a21c25167a964fb508 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Sat Mar 28 23:56:22 2015 -0500 fmap: new API using region_device Instead of being pointer based use the region infrastrucutre. Additionally, this removes the need for arch-specific compilation paths. The users of the new API can use the region APIs to memory map or read the region provided by the new fmap API.

Aaron Durbin (adurbin(a)chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10260 -gerrit commit b8d14b116781c4d355fd271619658e586b0c1b12 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Tue May 19 16:32:54 2015 -0500 x86: fix mirror_payload() The api to mirror_payload() was changed, but as no board in coreboot.org selected MIRROR_PAYLOAD_TO_RAM_BEFORE_LOADING this issue was missed.
