The driver doesn't compile on (at least) x86 due (possibly among others) to missing readsw/writesw I/O accessors, restrict compilation to SUPERH or ARM. Whether the CTL_DMA_ENABLE register is part of the standard TMIO controller or is Renesas-specific is unknown and impossible to test as we have no current or planned TMIO DMA users other than SUPERH and ARCH_SHMOBILE. Writing to the register is thus conditionally compiled for SUPERH and ARCH_SHMOBILE only. Adding ARCH_SHMOBILE_MULTI to the list would extend this to multiarch kernels, but would break the driver for non-shmobile platforms if the register is Renesas-specific. We can thus get rid of the conditional compilation completely without introducing any further issue, and let future non-Renesas users deal with the situation if it turns out to be a the problem.
