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 3d4efca358193074f507395295d6820adbaf3a31
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.

commit e487d4998aa1b03ba10910707674519b3dbe939f
Author: Aaron Durbin <adurbin(a)chromium.org>

cbfs: remove unused CBFS_HEADER_ROM_OFFSET option
The CBFS_HEADER_ROM_OFFSET went away. Remove remaining
defintions that are not used.

Patch set updated for coreboot: 6868b2b fmap: new API using region_device

commit 6868b2ba56310c7dec7e420db155e48ccaaf9c24
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.

Patch set updated for coreboot: 6ae1da3 x86: garbage collect SMM programs
by Aaron Durbin 15 May '15
by Aaron Durbin 15 May '15
15 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/10219
-gerrit
commit 6ae1da3c609e3c0ebfa7143e2b3389dd8c4f281a
Author: Aaron Durbin <adurbin(a)chromium.org>
Date: Fri May 15 15:23:39 2015 -0500
x86: garbage collect SMM programs
The non-module SMM programs were not being garbage collected
during linking. Do this so that one doesn't have to add dependencies
for unused functions in SMM.
TEST=Interrogated readelf -e smm.elf on both builds as well as diffed
the symbol table. Runtime testing was not done.

Aaron Durbin (adurbin(a)chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10225
-gerrit
commit 394095ecb1edf8477b11ece38981a67e3c0b13ad
Author: Aaron Durbin <adurbin(a)chromium.org>
Date: Fri May 15 23:25:46 2015 -0500
vboot: move to region_devices
Now that vboot is using offsets for everything remove the
pass through vboot_get_region() and use region_devices
as first class citizens.

Aaron Durbin (adurbin(a)chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10224
-gerrit
commit 08a1a368af2dc6a14402d328b9de90639d878707
Author: Aaron Durbin <adurbin(a)chromium.org>
Date: Fri May 15 23:21:13 2015 -0500
boot_device: add sub region helper
Provide boot_device_ro_subregion() which handles the logic
of making sub regions of the read-only boot device. Utilize
the helper in the famp library.

Patch set updated for coreboot: 96117fd cbfs: add 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/9134
-gerrit
commit 96117fd396b67caab035e0f893a26d3f3488802c
Author: Aaron Durbin <adurbin(a)chromium.org>
Date: Fri May 15 23:39:23 2015 -0500
cbfs: add new API using region_device
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.

Aaron Durbin (adurbin(a)chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10225
-gerrit
commit 696a8d05d21d387e3862326d926c8c90d418855d
Author: Aaron Durbin <adurbin(a)chromium.org>
Date: Fri May 15 23:25:46 2015 -0500
vboot: move to region_devices
Now that vboot is using offsets for everything remove the
pass through vboot_get_region() and use region_devices
as first class citizens.
Change-Id: I1a86f3725e5bce38e6ca31e9641b1a8f4ac50e96
Signed-off-by: Aaron Durbin <adurbin(a)chromium.org>

New patch to review for coreboot: 307493e boot_device: add sub region helper

commit 307493ec00821ded182b4ead4f53c6694ee19a59
Author: Aaron Durbin <adurbin(a)chromium.org>
Date: Fri May 15 23:21:13 2015 -0500
boot_device: add sub region helper
Provide boot_device_ro_subregion() which handles the logic
of making sub regions of the read-only boot device. Utilize
the helper in the famp library.
