Paul Burton 3ffc17d876 MIPS: Adjust MIPS64 CAC_BASE to reflect Config.K0 ... On MIPS64 we define the default CAC_BASE as one of the xkphys regions of the virtual address space. Since the CCA is encoded in bits 61:59 of xkphys addresses, fixing CAC_BASE to any particular one prevents us from dynamically changing the CCA as we do for MIPS32 where CAC_BASE is placed within kseg0. In order to make the kernel more generic, drop the current kludge that gives CAC_BASE CCA=3 if CONFIG_DMA_NONCOHERENT is selected (disregarding CONFIG_DMA_MAYBE_COHERENT) & CCA=5 (which is not standardised by the architecture) otherwise. Instead read Config.K0 and generate the appropriate offset into xkphys, presuming that either the bootloader or early kernel code will have configured Config.K0 appropriately. This seems like the best option for a generic implementation. The ip27 spaces.h is adjusted to set its former value of CAC_BASE, since it's the only user of CAC_BASE from assembly (in its smp_slave_setup macro). This allows the generic case to focus solely on C code without breaking ip27.
