platform/x86: acerhdf: Add BIOS entry for Gateway LT31 v1.3307

2018-11-27T15:08:00+00:00

[ Upstream commit 684238d79ad85c5e19a71bb5818e77e329912fbc ] To fix: acerhdf: unknown (unsupported) BIOS version Gateway /LT31 /v1.3307 , please report, aborting! As can be seen in the context, the BIOS registers haven't changed in the previous versions, so the assumption is they won't have changed in this last update for this somewhat older platform either.

platform/chrome: Use proper protocol transfer function

2018-03-24T09:58:47+00:00

[ Upstream commit d48b8c58c57f6edbe2965f0a5f62c5cf9593ca96 ] pkt_xfer should be used for protocol v3, and cmd_xfer otherwise. We had one instance of these functions correct, but not the second, fall-back case. We use the fall-back only when the first command returns an IN_PROGRESS status, which is only used on some EC firmwares where we don't want to constantly poll the bus, but instead back off and sleep/retry for a little while.
