[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 Signed-off-by: Nick Cheng <nick.cheng@areca.com.tw> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
