Hello,

This serie adds support for the iBT interface on Aspeed SOCs (AST2400
and AST2500). The BT (Block Transfer) interface is used to perform
in-band IPMI communication between a host and its BMC. This driver
implements the BMC side.

This looks good.  I pulled these into my tree, it's ok for 4.9 or
whatever is next, since it's a new driver.

Do patches 2 and 3 go through Joel?

-corey

Changes since v2:

  - limit to one opener
  - protect write/read operations with a mutex.

Changes since v1:

  - the driver is now called 'bt-bmc' and the device node '/dev/ipmi-bt-host'
- the code is now under drivers/char/ipmi/. This required a change of
    the top Makefile in drivers/ to compile the bt-bmc driver with the
    ipmi handlers not being selected. That might be an issue.
- changed the read/write operations to use a temporary buffer and get
    rid of the {get,put}_user calls

Thanks,

C.
