Dear Che-liang Chiou,

Should we not rather remove all this dead code again?
Until today there are no users for this code in mainline, and no patches have been submitted that intend to use it.
Chrome/Chromium OS uses TPM for its secure boot. So I would say it is quite a lot of usage on the critical path of booting.
I do not see any such code in mainline. So for mainline, this is just dead code, i. e. it adds maintenance efforts without benefit for any mainline users.
The code that uses TPM did not send to the mainline because the mainline did not have a TPM driver until very recently.
Well, the patche shave been submitted long time ago, so I would have expected to see such code soon after. But so far, nothign happened.
Now you are trying to add even more code, with still no users in sight.
And, I am still figuring out how to submit the TPM user code. I guess it would be better to organize it in a command-line toolkit so that it can be interleaved in between other commands. What do you think?
I don't understand what you mean. Didn't you just write there was code ready to be submitted? So that code is not ready and not intended for mainline?
Best regards,
Wolfgang Denk
