ipmi-hiomap implements the PNOR access control protocol formerly known
as "the mbox protocol" but uses IPMI instead of the AST LPC mailbox as a
transport. As there is no-longer any mailbox involved in this alternate
implementation the old protocol name is quite misleading, and so it has
been renamed to "the hiomap protoocol" (Host I/O Mapping protocol). The
same commands and events are used though this client-side implementation
assumes v2 of the protocol is supported by the BMC.
The code is a heavily-reworked copy of the mbox-flash source and is
introduced this way to allow for the mbox implementation's eventual
removal.
mbox-flash should in theory be renamed to mbox-hiomap for consistency,
but as it is on life-support effective immediately we may as well just
remove it entirely when the time is right.
