* powerpc: Merge remaining RTAS codePaul Mackerras2005-11-0311-161/+143
| | | | | | | | | This moves rtas-proc.c and rtas_flash.c into arch/powerpc/kernel, since cell wants them as well as pseries (and chrp can use rtas-proc.c too, at least in principle). rtas_fw.c is gone, with its bits moved into rtas_flash.c and rtas.c.

| * [PATCH] powerpc: Move naca.h to platforms/iseriesDavid Gibson2005-11-025-4/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | These days, the NACA only exists on iSeries. Therefore, this patch moves naca.h from include/asm-ppc64 to arch/powerpc/platforms/iseries. There was one file including naca.h outside of platforms/iseries - arch/ppc64/kernel/udbg_scc.c. However, that's obviously a hangover from older days. The include is not necessary, so this patch simply removes it. Built and booted on iSeries, built for G5 (which uses udbg_scc.o).

| * [PATCH] powerpc: Move dart.hDavid Gibson2005-11-022-2/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | asm-ppc64/dart.h is included in exactly one place - arch/powerpc/sysdev/u3_iommu.c. This patch, therefore, moves it into arch/powerpc/sysdev. While we're at it, update the #ifndef/#define protecting the include, and the filename in the comments of u3_iommu.c. Built and booted on pSeries and G5, built for ppc32 powermac.

* | | [PATCH] powerpc: Merge bitops.hDavid Gibson2005-11-016-188/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here's a revised version. This re-introduces the set_bits() function from ppc64, which I removed because I thought it was unused (it exists on no other arch). In fact it is used in the powermac interrupt code (but not on pSeries). - We use LARXL/STCXL macros to generate the right (32 or 64 bit) instructions, similar to LDL/STL from ppc_asm.h, used in fpu.S - ppc32 previously used a full "sync" barrier at the end of test_and_*_bit(), whereas ppc64 used an "isync". The merged version uses "isync", since I believe that's sufficient. - The ppc64 versions of then minix_*() bitmap functions have changed semantics. Previously on ppc64, these functions were big-endian (that is bit 0 was the LSB in the first 64-bit, big-endian word). On ppc32 (and x86, for that matter, they were little-endian. As far as I can tell, the big-endian usage was simply wrong - I guess no-one ever tried to use minixfs on ppc64. - On ppc32 find_next_bit() and find_next_zero_bit() are no longer inline (they were already out-of-line on ppc64). - For ppc64, sched_find_first_bit() has moved from mmu_context.h to the merged bitops. What it was doing in mmu_context.h in the first place, I have no idea. - The fls() function is now implemented using the cntlzw instruction on ppc64, instead of generic_fls(), as it already was on ppc32. - For ARCH=ppc, this patch requires adding arch/powerpc/lib to the arch/ppc/Makefile. This in turn requires some changes to arch/powerpc/lib/Makefile which didn't correctly handle ARCH=ppc. Built and running on G5.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The nvram code formally known as bpa_nvram.c is rather generic really, so it is quite likely to be useful to future boards not based on cell.
