190 * Miscellaneous SBP2 related config rom defines
194 * The status fifo address definition below is used as a status base, with a chunk
195 * separately assigned for each sbp2 device detected. For example, 0xfffe00000000ULL
196 * is used for the first sbp2 device detected, 0xfffe00000020ULL for the next sbp2
199 * Note: We could use a single status fifo address for all sbp2 devices, and figure
200 * out which sbp2 device the status belongs to by looking at the source node id of
201 * the status write... but, using separate addresses for each sbp2 device allows for
202 * better code and the ability to support multiple luns within a single 1394 node.
204 * Also note that we choose the address range below as it is a region specified for
205 * write posting, where the ohci controller will automatically send an ack_complete
206 * when the status is written by the sbp2 device... saving a split transaction. =)
