b0a36f6a91 Update message ring handling code for XLR/XLS
- Wakeup multiple threads per core using message ring watermark interrupts.
- Update message ring handler registration, use the real device station id
  for registering interrupts.
- rge/nlge: update for the new message ring registration code.
- rge/nlge: use 2 message ring stations for incoming packets, this will
  allow more messages to be queued.
- nlge: comment fixes, remove unused variable
- style and whitespace fixes

c42040571e Fixes for XLR network accelerator driver (nlge).
- Process some tx done messages in the transmit path, to ensure that
  the XLR NA tx done FIFO does not overflow.
- Add a message ring handler API to process atmost a given number of
  messages from a specified bucket mask. This will be used to process
  the tx done messages
- Add a callout to restart transmit in the case transmit gets blocked.
- Update enable_msgring_int() and disable_msgring_int(), remove unused
  args and make static.

480f6157fb sys/mips/rmi/msgring.h - fixes and clean up.
- Remove sync from msgrng_send, sync needs to be called just once before
  sending.
- Fix retry logic - don't reload registers when retrying in message_send,
  also fix check for send pending fail.
- remove unused message_send_block_fast()
- merge message_receive_fast() to message_receive
- style(9) fixes, and comments
- rge and nlge updated for the sys/mips/rmi/msgring.h changes

670a090971 Clean up fast message ring code for XLR.
Fix message ring send path:
- define msgrng_access_enable() which disables local interrupts
  and enables message ring access. Also define msgrng_restore() which
  restores interrupts
- remove all other msgrng enable/disable macros, no need of critical_enter
  and other locking here.
- message_send() fixup: re-read status until pending bit clears
- message_send_retry() fixup: retry only few times with interrupts disabled
- Fix up message_send/message_send_retry callers - call
  msgrng_access_enable() and msgrng_restore() correctly so that interrupts
  are not disabled for long.
- removed unused and obsolete code from sys/mips/rmi/msgring.h
- some style fixes - more later

rge.c (XLR GMAC driver):
- updated for the message ring changes
- remove unused message_send_block()
- retry on credit failure, this is not a permanent failure when credits
  are configured correctly. Add panic if credits are not available to
  send for a long time.

79994806a1 Move debug.h to the the rge driver directory. rge.c is the only user of
debug.h. Remove debug.h references from other files.

61b993a34f Clean up header files in RMI platform code (sys/mips/rmi), and remove
unused files.

- remove clock.c and clock.h, these are not used after the new timer
  code was added.
- remove duplicated include files, fix header file ordering, remove
  some unneeded includes.
- rename mips/rmi/shared_structs.h which contains the RMI boot loader
  interface to mips/rmi/rmi_boot_info.h. Remove unused files
  mips/rmi/shared_structs_func.h and sys/mips/rmi/shared_structs_offsets.h
- merge mips/rmi/xlrconfig.h and mips/rmi/rmi_mips_exts.h, and remove
  duplicated functions.
- nlge - minor change to remove unneeded argument.
- Add FreeBSD svn keyword for headers

30eb8eda72 XLR PIC code update and style(9) fixes.
- style(9) fixes to mips/rmi platform files
- update pic.h to add pic_setup_intr() and use pic_setup_intr() for setting
  up interrupts which are routed thru PIC.
- remove rmi_spin_mutex_safe and haslock, and make sure that the functions
  are called only after mutexes are available.

7a7f91f61b ok we now get so that the uart init's and we can print. We
cannot set baud rate as they did in 6.4, this hoses things and
we loose our 38400 default term.

We now lock somewhere in tcinit.

257c916acf More initial RMI files. Note that these so far do NOT
compile and many of them may disappear. For example
the xlr_boot1_console.c is old code that is ifdef'd out.
I will clean these sorts of things up as I make progress
on the port. So far the only thing I have I think straightened
out is the bits around the interupt handling... and hey that
may be broke ;-)
