Hi Charlotte,

here are some description of the EC in your board. Don't know how much
you already know.

The Thinkpad has 2 EC controller.

1x Thinker
1x H8S (W530 has a SMSC chip).

The ectool dump only shows a buffer, which both side(host+ec) can use to

The ectool usually talks to the H8S and not to the Thinker. There is a
way to community to the Thinker using different I/O address.

   | LPC
| H8S |
   | SPI
