Unlike already implemented Keyboard Controller Style (KCS) interface
Block Transfer interface is not byte-oriented and implies that device is
capable of buffering a command before processing it. Another difference
is that polling can be replaced with interrupts, though this isn't used
by this implementation.
More details can be found in "Intelligent Platform Management Interface
Specification", v2.0, Rev. 1.1:

This was initially tested on Talos II (OpenPower platform) by Raptor
Computing Systems. Later versions were tested using QEMU and ipmi_sim
from OpenIPMI project as well as QEMU's builtin BMC simulator.
