powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00+00:00

from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras

[POWERPC] 4xx: Add PPC4xx L2-cache support (440GX)

2008-03-26T12:27:54+00:00

This patch adds support for the 256k L2 cache found on some IBM/AMCC 4xx PPC's. It introduces a common 4xx SoC file (sysdev/ppc4xx_soc.c) which currently "only" adds the L2 cache init code. Other common 4xx stuff can be added later here. The L2 cache handling code is a copy of Eugene's code in arch/ppc with small modifications. Tested on AMCC Taishan 440GX.

[POWERPC] 4xx: Improve support for 4xx indirect DCRs

2007-12-23T19:12:11+00:00

Accessing indirect DCRs is done via a pair of address/data DCRs. Such accesses are thus inherently racy, vs. interrupts, preemption and possibly SMP if 4xx SMP cores are ever used. This updates the mfdcri/mtdcri macros in dcr-native.h (which were so far unused) to use a spinlock. In addition, add some common definitions to a new dcr-regs.h file.
