New Revision: 202035

Log:
Merge from projects/mips to head by hand:
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.

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.
r196836 | gonzo | 2009-09-04 13:02:11 -0600 (Fri, 04 Sep 2009) | 2 lines
- Clean out some XXXMIPS comments that's not relevant now
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.
r195496 | imp | 2009-07-09 09:04:52 -0600 (Thu, 09 Jul 2009) | 2 lines
Don't force ISA_MIPS32.
r195495 | imp | 2009-07-09 09:04:24 -0600 (Thu, 09 Jul 2009) | 4 lines
Make the yamon function pointer stuff 64-bit safe. Make the base
unsigned long, and sign extend the address of the function we're
calling through.
r195494 | imp | 2009-07-09 08:54:09 -0600 (Thu, 09 Jul 2009) | 3 lines
Addresses should be unsigned long. Make the address constants
unsigned long.
r194929 | gonzo | 2009-06-24 16:42:52 -0600 (Wed, 24 Jun 2009) | 6 lines
- Do not use hardcoded uart speed
- Call mips_timer_early_init before initializing uart in order
to make DELAY usable for ns8250 driver
Submitted by: Neelkanth Natu
r194212 | gonzo | 2009-06-14 14:54:46 -0600 (Sun, 14 Jun 2009) | 2 lines
- Fix prototypes to make compiler happy
r192864 | gonzo | 2009-05-26 16:40:12 -0600 (Tue, 26 May 2009) | 4 lines
- Replace CPU_NOFPU and SOFTFLOAT options with CPU_FPU. By default
we assume that there is no FPU, because majority of SoC does
not have it.
r192788 | gonzo | 2009-05-25 22:51:56 -0600 (Mon, 25 May 2009) | 3 lines
- Provide proper pre_thread/post_ithread functions for GT PCI
controller.
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.
r191084 | gonzo | 2009-04-14 20:28:26 -0600 (Tue, 14 Apr 2009) | 6 lines
Use FreeBSD/arm approach for handling bus space access: space tag is a pointer
to bus_space structure that defines access methods and hence every bus can
define own accessors. Default space is mips_bus_space_generic. It's a simple
interface to physical memory, values are read with regard to host system
byte order.
