Cover letter [PATCH 0/2] SWIOTLB support for Netlogic XLP
Two patches for using the SWIOTLB lib in Netlogic XLP code.
The first one adds support for SWIOTLB in generic MIPS operations. Without this platforms cannot use generic MIPS dma ops when SWIOTLB is enabled. The second adds SWIOTLB based dma ops for Netlogic XLP, which will be used by a few drivers which cannot do 64-bit DMA.
Comments welcome.
Regards,
JC.
