The driver is not used anywhere. It is a dead code and it seems to be falling apart slowly due to bitrot. Remove this driver.

This driver is used in several chromeOS devices which have not quite made it upstream yet. Why does it seem falling apart?

Noone tested it every since, it seems unmaintained to me. This it is only logical to drop it if there are no users. Will the chromium devices ever make it upstream?

The TPM code is used by coreboot and Tegra Seaboard, both of which are upstream. We are working hard on a third :-)

If there is a build problem, please can you let us know?

Regards, Simon
