MIPS: Join the coherent domain when a CM is present MIPS Linux expects the bootloader to leave the boot CPU a member of the coherent domain when running on a system with a CM, and we will need to do so if we wish to make use of IOCUs to have cache-coherent DMA in U-Boot (and on some systems there is no choice in that matter). When a CM is present, join the coherent domain after completing cache initialisation. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
