; 53c710 driver.  Modified from Drew Eckhardts driver
; for 53c810 by Richard Hirst [richard@sleepie.demon.co.uk]
;
; I have left the script for the 53c8xx family in here, as it is likely
; to be useful to see what I changed when bug hunting.

; IMPORTANT : This code is self modifying due to the limitations of 
;	the NCR53c7,8xx series chips.  Persons debugging this code with
;	the remote debugger should take this into account, and NOT set
;	breakpoints in modified instructions.
;
; Design:
; The NCR53c7,8xx family of SCSI chips are busmasters with an onboard 
; microcontroller using a simple instruction set.   
;
; So, to minimize the effects of interrupt latency, and to maximize 
; throughput, this driver offloads the practical maximum amount 
; of processing to the SCSI chip while still maintaining a common
; structure.
;
; Where tradeoffs were needed between efficiency on the older
; chips and the newer NCR53c800 series, the NCR53c800 series 
; was chosen.
;
; While the NCR53c700 and NCR53c700-66 lacked the facilities to fully
; automate SCSI transfers without host processor intervention, this 
; isn't the case with the NCR53c710 and newer chips which allow 
;
; - reads and writes to the internal registers from within the SCSI
; 	scripts, allowing the SCSI SCRIPTS(tm) code to save processor
; 	state so that multiple threads of execution are possible, and also
; 	provide an ALU for loop control, etc.
; 
; - table indirect addressing for some instructions. This allows 
;	pointers to be located relative to the DSA ((Data Structure
;	Address) register.
;
; These features make it possible to implement a mailbox style interface,
; where the same piece of code is run to handle I/O for multiple threads
; at once minimizing our need to relocate code.  Since the NCR53c700/
; NCR53c800 series have a unique combination of features, making a 
; a standard ingoing/outgoing mailbox system, costly, I've modified it.
;
; - Mailboxes are a mixture of code and data.  This lets us greatly
; 	simplify the NCR53c810 code and do things that would otherwise
;	not be possible.
;
; The saved data pointer is now implemented as follows :
;
; 	Control flow has been architected such that if control reaches
;	munge_save_data_pointer, on a restore pointers message or 
;	reconnection, a jump to the address formerly in the TEMP register
;	will allow the SCSI command to resume execution.
;

;
; Note : the DSA structures must be aligned on 32 bit boundaries,
; since the source and destination of MOVE MEMORY instructions 
; must share the same alignment and this is the alignment of the
; NCR registers.
;

; For some systems (MVME166, for example) dmode is always the same, so don't
; waste time writing it

; Once a device has initiated reselection, we need to compare it 
; against the singly linked list of commands which have disconnected
; and are pending reselection.  These commands are maintained in 
; an unordered singly linked list of DSA structures, through the
; DSA pointers at their 'centers' headed by the reconnect_dsa_head
; pointer.
; 
; To avoid complications in removing commands from the list,
; I minimize the amount of expensive (at eight operations per
; addition @ 500-600ns each) pointer operations which must
; be done in the NCR driver by precomputing them on the 
; host processor during dsa structure generation.
;
; The fixed-up per DSA code knows how to recognize the nexus
; associated with the corresponding SCSI command, and modifies
; the source and destination pointers for the MOVE MEMORY 
; instruction which is executed when reselected_ok is called
; to remove the command from the list.  Similarly, DSA is 
; loaded with the address of the next DSA structure and
; reselected_check_next is called if a failure occurs.
;
; Perhaps more concisely, the net effect of the mess is 
;

; data_transfer  
; other_out
; other_in
; other_transfer
;
; PURPOSE : handle the main data transfer for a SCSI command in 
;	several parts.  In the first part, data_transfer, DATA_IN
;	and DATA_OUT phases are allowed, with the user provided
;	code (usually dynamically generated based on the scatter/gather
;	list associated with a SCSI command) called to handle these 
;	phases.
;
;	After control has passed to one of the user provided 
;	DATA_IN or DATA_OUT routines, back calls are made to 
;	other_transfer_in or other_transfer_out to handle non-DATA IN
;	and DATA OUT phases respectively, with the state of the active
;	data pointer being preserved in TEMP.
;
;	On completion, the user code passes control to other_transfer
;	which causes DATA_IN and DATA_OUT to result in unexpected_phase
;	interrupts so that data overruns may be trapped.
;
; INPUTS : DSA - SCSI command
;
; CALLS : OK in data_transfer_start, not ok in other_out and other_in, ok in
;	other_transfer
;
; MODIFIES : SCRATCH
;
; EXITS : if STATUS IN is detected, signifying command completion,
;	the NCR jumps to command_complete.  If MSG IN occurs, a 
;	CALL is made to msg_in.  Otherwise, other_transfer runs in 
;	an infinite loop.

; PURPOSE : process messages from a target.  msg_in is called when the 
;	caller hasn't read the first byte of the message.  munge_message
;	is called when the caller has read the first byte of the message,
;	and left it in SFBR.  msg_in_restart is called when the caller 
;	hasn't read the first byte of the message, and wishes RETURN
;	to transfer control back to the address of the conditional
;	CALL instruction rather than to the instruction after it.
;
;	Various int_* interrupts are generated when the host system
;	needs to intervene, as is the case with SDTR, WDTR, and
;	INITIATE RECOVERY messages.
;
;	When the host system handles one of these interrupts,
;	it can respond by reentering at reject_message, 
;	which rejects the message and returns control to
;	the caller of msg_in or munge_msg, accept_message
;	which clears ACK and returns control, or reply_message
;	which sends the message pointed to by the DSA 
;	msgout_other table indirect field.
;
;	DISCONNECT messages are handled by moving the command
;	to the reconnect_dsa_queue.

; NOTE: DSA should be valid when we get here - we cannot save both it
;	and TEMP in this routine.

;

;
; PURPOSE : handle command termination when STATUS IN is detected by reading
;	a status byte followed by a command termination message. 
;
;	Normal termination results in an INTFLY instruction, and 
;	the host system can pick out which command terminated by 
;	examining the MESSAGE and STATUS buffers of all currently 
;	executing commands;
;
;	Abnormal (CHECK_CONDITION) termination results in an
;	int_err_check_condition interrupt so that a REQUEST SENSE
;	command can be issued out-of-order so that no other command
;	clears the contingent allegiance condition.
;	
;
; INPUTS : DSA - command	
;
; CALLS : OK
;
; EXITS : On successful termination, control is passed to schedule.
;	On abnormal termination, the user will usually modify the 
;	DSA fields and corresponding buffers and return control
;	to select.

;
; wait_reselect
;
; PURPOSE : This is essentially the idle routine, where control lands
;	when there are no new processes to schedule.  wait_reselect
;	waits for reselection, selection, and new commands.
;
;	When a successful reselection occurs, with the aid 
;	of fixed up code in each DSA, wait_reselect walks the 
;	reconnect_dsa_queue, asking each dsa if the target ID
;	and LUN match its.
;
;	If a match is found, a call is made back to reselected_ok,
;	which through the miracles of self modifying code, extracts
;	the found DSA from the reconnect_dsa_queue and then 
;	returns control to the DSAs thread of execution.
;
; INPUTS : NONE
;
; CALLS : OK
;
; MODIFIES : DSA,
;
; EXITS : On successful reselection, control is returned to the 
;	DSA which called reselected_ok.  If the WAIT RESELECT
;	was interrupted by a new commands arrival signaled by 
;	SIG_P, control is passed to schedule.  If the NCR is 
;	selected, the host system is interrupted with an 
;	int_err_selected which is usually responded to by
;	setting DSP to the target_abort address.
