Patch set updated for coreboot: 2245333 cbfs: add new API using region_device
by Aaron Durbin 16 May '15

16 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/9134 -gerrit commit 224533337916493482701dfdb0470bba958e4ca9 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.

Patch set updated for coreboot: ea084a8 cbfs: add new API using region_device
by Aaron Durbin 16 May '15

16 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/9134 -gerrit commit ea084a8539d2b3ac857a6e18aa6a50985d142e4f 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.
