Re: [PATCH v3 2/2] rpmb: add a virtio RPMB device driver

[sashiko-bot@kernel.org]

> From: Haruka Kuze <harukak@zohomail.eu>
> 
> No driver exists for virtio-rpmb devices (virtio ID 28), so OP-TEE
> running in a guest can not use them.
> 
> This registers the virtio-rpmb devices found with the RPMB sub-system.
> Each request is done in one transfer on request queue, and for key
> programming and data writing a result read frame is appended so that
> the device can return the result.
> 
> These frames are copied since the caller's buffers are not always
> usable for DMA.
> 
> These frames follow the emmc definition, so that the device is
> registered as RPMB_TYPE_EMMC. The device has no identifier of own, so
> that a fixed dev_id is used for the key derivation for the device.
> 
> Based on the virtio-rpmb driver in Alex Bennée's RPMB series.
