2011-07-25drm/radeon: Writeback endian fixesBenjamin Herrenschmidt1-3/+0
The writeback ring pointer and IH ring pointer are read using le32_to_cpu so we do not want the chip to byteswap them on big-endian. We still want to byteswap the ring itself and the IBs, so we don't touch that but we remove setting of the byteswap bits in CP_RB_RPTR_ADDR and IH_CNTL. In general, for things like that where we control all the accessors easily, we are better off doing the swap in SW rather than HW. Paradoxally, it does keep the code closer to x86 and avoid using poorly tested HW features. I also changed the use of RADEON_ to R600_ in a couple of cases to be more consistent with the surrounding code.
