Subject: Aw: [PATCH v2 0/2] tpm: add driver for cr50 on SPI
Date: Mon, 25 Jul 2016 19:09:21 +0200 [thread overview]
Message-ID: <trinity-26286f32-3045-4711-8972-ee0964b74003-1469466561717@3capp-gmx-bs15> (raw)

Hi Andrey,
thanks for the update.
> This patchset adds support for H1 Secure Microcontroller running
> Cr50 firmware. It implements several functions, including TPM-like
> functionality, and communicates over SPI using the FIFO protocol
> described in the PTP Spec, section 6.
> H1 is a proprietary chip that the Chrome OS team is investigating
> for inclusion in future Chromebooks.
so is this "broken" device already in the field? (i.e. can I buy it? how many of them)
from the description it seems not. ("future chromebooks")
--> how likely is it that the firmware of that device will be fixed that it can work with the regular driver?
Although I really like to see driver upstreamed, I also want to avoid maintenance hell for obscure hardware :/
Thanks,
Peter
