From ae52e7f09ff509df11cd408eabe90132b6be1231 Mon Sep 17 00:00:00 2001

Subject: [PATCH] [SCSI] arcmsr: Support 1024 scatter-gather list entries and
improve AP while FW trapped and behaviors of EHs
1. To support 4M/1024 scatter-gather list entry, reorganize struct
ARCMSR_CDB and struct CommandControlBlock
2. To modify arcmsr_probe
3. In order to help fix F/W issue, add the driver mode for type B card
4. To improve AP's behavior while F/W resets
5. To unify struct MessageUnit_B's members' naming in all OS drivers'
6. To improve error handlers, arcmsr_bus_reset(), arcmsr_abort()
7. To fix the arcmsr_queue_command() in bus reset stage, just let the
commands pass down to FW, don't block
