I think this is what you're looking for:
It contains the commit hash, build config, and a few other logs for each
device/commit.  It is user submitted though, since there doesn't exist a
test setup for every supported device.

Right now, I'm the main builder/distributor of upstream coreboot firmware
for ChromeOS devices; I support all Haswell, Broadwell, and some Baytrail
devices, the former with both UEFI and Legacy Boot variants. When time
permits, I'll expand that to cover the rest of the Baytrail devices, then
move on to adding support for Skylake.  No plans for Braswell support
unless I acquire a device on which to test.

John Lewis has some upstream firmware for the older SandyBridge/IvyBridge
models, but his Haswell firmware is build from Google's tree/branches not
upstream.  He also has no plans for any future upstream firmware.
