4b7ec27007 - There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
  since r52045) but even recently added device drivers do this unnecessarily.
  Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.
  Discussed with: jhb
- Also while at it, use __FBSDID.

b67d11bbcc Change rman_manage_region() to actually honor the rm_start and rm_end
constraints on the rman and reject attempts to manage a region that is out
of range.
- Fix various places that set rm_end incorrectly (to ~0 or ~0u instead of
  ~0ul).
- To preserve existing behavior, change rman_init() to set rm_start and
  rm_end to allow managing the full range (0 to ~0ul) if they are not set by
  the caller when rman_init() is called.

8d4380adbf PCI fix for XLR C revision chips, limit DMA address to the first 2GB
physical address.  Adds a dma tag to the XLR/XLS pci bus with the
lowaddr if the CPU happens to be a XLR C rev.

da4dad492d XLS B0 revision PCI support and related changes.
- XLS B0 and later revision chips have PCIe link 2 & 3 mapped to different
  PIC interrupts. Update pic.h, board.h and xlr_pci.c to reflect this.
- remove debug prints in xlr_pci.c
- add more processor IDs to board.h, add function xlr_is_xls_b0()
- some style(9) and whitespace fixes

2e4e56742e Clean up and update sys/mips/rmi/rmi_mips_exts.h
- Provide 64 bit implementations for some macros. On n64 and n32,
  don't split 64 bit values.
- No need for 32 bit ops for control registers.
- Fix few bugs (write control reg, write_c0_register64).
- Re-write EIRR/EIMR/CPUID operations using read_c0_registerXX, no
  need of inline assembly.
- rename control reg access functions to avoid phnx, update callers.
- stlye/whitespace fixes.

36a7e25854 PCIe updates for XLS.
Fix interrupt routing so that the irq returned is correct for XLR and
XLS. This also updates the MSI hack we had earlier - we still don't
really support MSI, but we support some drivers that use MSI, by providing
support for allocating one MSI per pci link - this MSI is directly
mapped to the link IRQ.

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.

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

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

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 ;-)
