MIPS: Netlogic: Fix DMA zone selection for 64-bit
Jayachandran C [Wed, 31 Oct 2012 12:01:33 +0000 (12:01 +0000)]
Fix Kconfig for both XLR and XLP to select ZONE_DMA32 (instead of ZONE_DMA)
in case of 64-bit compilation. This can be used for devices that can only
do DMA to 32-bit address. ZONE_DMA is not useful on XLR or XLP.
