5543a1b98e Devices that rely on hints or identify routines for discovery need to
return BUS_PROBE_NOWILDCARD from their probe routines to avoid claiming
wildcard devices on their parent bus. Do a sweep through the MIPS tree.

bb15db8f16 RMI security accelerator driver update.
- Compile fixes for 9.0, the previous version of this driver was
  for FreeBSD 6.
- Add virtual address field in OperationDescriptor_t, we cannot use
  MIPS_PHYS_TO_KSEG0 on physical address.
- Fixes for new message ring API
- Remove unused sys/mips/rmi/dev/sec/stats.h
- Whitespace fixes

96001a35e1 XLR/XLS hardware interrupts should be programmed level triggered at the
PIC.  This should fix the interrupt releated issues seen after the
interrupt handling re-write for SMP.

833182b77e Updates for the RMI MIPS platform code
- set cache_coherent_dma flag in cpuinfo for XLR, this will make sure that
  BUS_DMA_COHERENT flag is handled correctly in busdma_machdep.c
- iodi.c, call device_get_name() just once
- clear RMI specific EIRR while intializing CPUs
- remove debug print in intr_machdep.c

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

d12f1e190e New driver nlge for XLR/XLS Network Accelerator. This will support the XGMAC
and XAUI 10G interfaces in addition RGMII/SGMII 1G interfaces.  This driver
is work in progress.

board.c and board.h expanded to include more info.

Only one of rge and nlge can be enabled at a time, rge will be deprecated
when nlge stabilizes.

b47f51b4a0 Revamp XLR interrupt handling, the previous scheme does not work well on
SMP.

We used to route all PIC based interrupts to cpu 0, and used the per-CPU
interrupt mask to enable/disable interrupts. But the interrupt threads can
run on any cpu on SMP, and the interrupt thread will re-enable the interrupts
on the CPU it runs on when it is done, and not on cpu0 where the PIC will
still send interrupts to.

The fix is move the disable/enable for PIC based interrupts to PIC, we will
ack on PIC only when the interrupt thread is done, and we do not use the
per-CPU interrupt mask.

The changes also introduce a way for subsystems to add a function that
will be called to clear the interrupt on the subsystem. Currently This is
used by the PCI/PCIe for doing additional work during the interrupt
handling.

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.

5574a166c9 64 bit compilation support XLR platform code.
Mostly changes to make casting between int and pointer and printing
64bit values safe for 32 and 64 bit compile.

4542827d4d This pushes all of JC's patches that I have in place. I
am now able to run 32 cores ok.. but I still will hang
on buildworld with a NFS problem. I suspect I am missing
a patch for the netlogic rge driver.

JC check and see if I am missing anything except your
core-mask changes

6b9c94873a - Move rmi_pci_bus_space to header and avoid extern
- remove unused and commented code (MIPS_BUS_SPACE_PCI, pic_usb_ack)
- use rmi_pci_bus_space for USB too (needs byteswap)
- uncomment xls_ehci.c in files.xlr
- changes to xls_ehci.c - updated with dev/usb/controller/ehci_*.c as

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 ;-)
