r201881 | imp | 2010-01-08 20:08:22 -0700 (Fri, 08 Jan 2010) | 3 lines
Rename mips_pcpu_init to mips_pcpu0_init since it applies only to the
BSP.  Provide a missing prototype.

r201845 | imp | 2010-01-08 15:48:21 -0700 (Fri, 08 Jan 2010) | 2 lines
Centralize initialization of pcpu, and set curthread early...

r201631 | neel | 2010-01-05 23:42:08 -0700 (Tue, 05 Jan 2010) | 5 lines
Remove all CFE-specific code from locore.S. The CFE entrypoint initialization
is now done in platform-specific code.
Approved by: imp (mentor)

With this commit our friend RMI will now compile. I have
not tested it and the chances of it running yet are about
ZERO.. but it will now compile. The hard part now begins,
 making it run ;-)

r198154 | rrs | 2009-10-15 15:03:32 -0600 (Thu, 15 Oct 2009) | 10 lines

Does 4 things:
1) Adds future RMI directories
2) Places intr_machdep.c in specfic files.arch pointing to the generic
   intr_machdep.c.  This allows us to have an architecture dependant
   intr_machdep.c (which we will need for RMI) in the machine specific
   directory
3) removes intr_machdep.c from files.mips
4) Adds some TARGET_XLR_XLS ifdef's for the machine specific intra_machdep.h. We
   may need to look at finding a better place to put this. But first I want to
   get this thing compiling.

r196236 | imp | 2009-08-14 19:03:13 -0600 (Fri, 14 Aug 2009) | 3 lines
Fix style error replicated multiple times.  Move to
mips_bus_space_generic for octeon obio impl.

r191282 | gonzo | 2009-04-19 16:02:14 -0600 (Sun, 19 Apr 2009) | 3 lines
- Make mips_bus_space_generic be of type bus_space_tag_t instead of
    struct bus_space and update all relevant places.

r187415 | gonzo | 2009-01-18 16:49:02 -0700 (Sun, 18 Jan 2009) | 3 lines
- Move Silicon Backplanes code out to system-wide level (dev/siba) as
    it's going to be used not only for siba5 devices.
