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. r198669 | rrs | 2009-10-30 02:53:11 -0600 (Fri, 30 Oct 2009) | 5 lines 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.
