2008-12-21	powerpc/4xx: Extended DCR support v2	Benjamin Herrenschmidt	1	-1/+7
	This adds supports to the "extended" DCR addressing via the indirect mfdcrx/mtdcrx instructions supported by some 4xx cores (440H6 and later). I enabled the feature for now only on AMCC 460 chips.

2006-12-04	[POWERPC] Generic DCR infrastructure	Benjamin Herrenschmidt	1	-0/+39
	This patch adds new dcr_map/dcr_read/dcr_write accessors for DCRs that can be used by drivers to transparently address either native DCRs or memory mapped DCRs. The implementation for memory mapped DCRs is done after the binding being currently worked on for SLOF and the Axon chipset. This patch enables it for the cell native platform Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
