*	[POWERPC] More DCR native fixups	David Gibson	2007-02-16	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Getting BenH's new EMAC driver working on 440GP, I found some more problems in the native mode paths of the new DCR code: - dcr_map() is supposed to return a dcr_host_t, but the native version is a macro that doesn't expand to an expression. With native DCRs, dcr_host_t is an empty structure, so we just use a constructor expression instead. - dcr_unmap() uses {} instead of the safer do {} while (0) idiom to implement a no-op Here's a fix.

*	[POWERPC] Only export __mtdcr/__mfdcr if CONFIG_PPC_DCR is set	Kumar Gala	2006-12-10	1	-2/+35
\| \| \| \| \| \| \| \| \| \|	On 85xx we don't build in dcr support because the core doesn't implement the instructions. This caused problems when building an 85xx kernel. Additionally made it so we only build __mtdcr/__mfdcr if we are CONFIG_PPC_DCR_NATIVE. The 85xx build issue wasPointed out by Dai Haruki. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
*	[POWERPC] Generic DCR infrastructure	Benjamin Herrenschmidt	2006-12-04	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>
