Patch set updated for coreboot: b967ac7 coreboot: introduce boot_device
by Aaron Durbin 20 May '15

20 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 b967ac78adc015030327ccb4dffc987770c1cee0 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: 8cbab0e asssets: abstract away the firmware assets used for booting
by Aaron Durbin 20 May '15

20 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 8cbab0ee5fb6da23ea2127bb5ff7c72e6c8cdd35 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Wed May 20 12:08:55 2015 -0500 asssets: 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: ef577b0 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 ef577b01b56976eec22c85869cb08f608d4f0e50 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: e262b6e prog_loading: add region_device representing memory

Aaron Durbin (adurbin(a)chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10261 -gerrit commit e262b6e6bcd293c8fad511e837c7a6b3bb2772f5 Author: Aaron Durbin <adurbin(a)chromium.org> Date: Tue May 19 16:25:20 2015 -0500 prog_loading: add region_device representing memory One can remove the struct buffer_area and use the region_device embedded in the struct prog to represent the in-memory loaded program. Do this by introducing a addrspace_32bit mem_region_device that can have region_device operations performed on it. The addrspace_32bit name was chosen to make it explicit that 32-bits of address space is supported at the max.

Patch set updated for coreboot: a7ffa3a cbfs: new API and better program loading
by Aaron Durbin 20 May '15

20 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 a7ffa3a8484ce1a8db9949b88f5db91da442598d Author: Aaron Durbin <adurbin(a)chromium.org> Date: Fri May 15 23:39:23 2015 -0500 cbfs: new API and better program loading 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 program loading takes advantage of those very properties by allowing multiple sources for locating a program. Because of this we can reduce the overhead of loading programs because it's all done in the common code paths. Only locating the program is per source.

New patch to review for coreboot: 3b5b94c asssets: abstract away the firmware assets used for booting
by Aaron Durbin 20 May '15

20 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 3b5b94c99cccc3a17ad0b64e05a34ded5daffc1c Author: Aaron Durbin <adurbin(a)chromium.org> Date: Wed May 20 12:08:55 2015 -0500 asssets: 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.
