Dear Simon,

I recommend to remove the whole TPM code instead.
It is actually used in the x86 Chromebook, but the patch to enable it never made it to mainline. There was quite a bit of push-back on the x86 side at the time and the person working on it finally had enough :-(
I have recently taken this up again to see if we can get x86 into a better state for newer Intel chips and the latest x86 Chromebooks. The patch to enable the TPM there is:
I don;t see how this uses it in any way in U-Boot. It still would not even compile most of the code, right?
I accept that it has sat there for a while without a board config to use it. But I would very much like to keep this code and see no sense in removing it now that it is actually in use.
Feel free to re-add it when there are any real users.
I've posted a removal patch.
Best regards,
Wolfgang Denk
