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.
