Patch merged into coreboot/master: cbfstool: rename checksum to attributes_offset
by gerrit＠coreboot.org 18 Jul '15

18 Jul '15

the following patch was just integrated into master: commit 0d618afc84db49e2248f9dff6ba21055830bc202 Author: Patrick Georgi <pgeorgi(a)chromium.org> Date: Wed Jul 15 18:28:23 2015 +0200 cbfstool: rename checksum to attributes_offset So far it's still unused, but its purpose will change: It will become an offset to another structure that contains additional file attributes. This change is compatible because the binary format doesn't change and so far the field was always set to 0, which can serve nicely as 'unused' field.

Patch merged into coreboot/master: libpayload: usb: xhci: Prevent address reuse
by gerrit＠coreboot.org 18 Jul '15

18 Jul '15

the following patch was just integrated into master: commit e44a4e8787b5388f63983c4460b495f53425162c Author: Julius Werner <jwerner(a)chromium.org> Date: Wed Jul 8 22:36:00 2015 -0700 libpayload: usb: xhci: Prevent address reuse We have been trying to avoid reassigning previously used USB addresses to different devices since CL:197420, because some devices seem to take issue with that. Unfortunately, that patch doesn't affect XHCI: those controllers insist on chosing addresses on their own. The only way to prevent them from reusing a previously assigned address is to not disable that slot at all. This patch implements address reuse avoidance on XHCI by not disabling slots when a device is detatched (which may occur both on physical detachment or if we simply couldn't find a driver for that device). Instead, we just release as many resources as we can for detached devices (by dropping all endpoint contexts) and defer the final cleanup until the point where the controller actually runs out of resources (a point that we probably don't often reach in most firmware scenarios). BRANCH=none BUG=chrome-os-partner:42181 TEST=Booted an Oak plugged into a Servo without having a driver for the SMSC network chip, observed that it could still enumerate the next device afterwards. Kept unplugging/replugging stuff until the cleanup triggered and made sure the controller still worked after that. Also played around a bit on a Falco without issues.
