[PATCH v3 0/3] ARM: aspeed: add support for the BT IPMI interface

[Cédric Le Goater]

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.

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.
