Read/write window property defines FFS partition file location. The BMC loads the PNOR partitions in a read-only volume. So after that there are following two cases: Read: Tries to open the file in read only mode from the partition(READONLY/READWRITE/PRESERVED), Partition Table tells the partition type depends on the offset. if file is not there in the mapped partition then tries to open the file from the read only partition. Write: Tries to open the file in write mode from the partition(READWRITE/PRESERVED), if file is not there in the mapped partition then mailbox daemon will copy the requested partition to the read-write volume to make changes to it.

This repo contains the protocol definition for the host to BMC mailbox communication specification which can be found in Documentation/mbox_procotol.md.
There is also a reference implementation of a BMC mailbox daemon, the details of which can be found in Documentation/mboxd.md.
Finally there is also an implementation of a mailbox daemon control program, the details of which can be found in Documentation/mboxctl.md.
