In the ARM64 and MIPs architectures, this is accomplished by CONFIG_ARCH_HAS_PHYS_TO_DMA=y and then defining the functions __dma_to_phys() and __phys_to_dma() accordingly. Doing so for the ARM architecture is not as easy as ARM64 and MIPS; the two functions are already defined as static inline functions. Howevery, the behavior of these functions may be changed by redefining the sub-functions that these two functions invoke. Specifically, this commit defines __arch_pfn_to_dma() __arch_dma_to_pfn() __arch_dma_to_virt() __arch_virt_to_dma() as these are the functions invoked by __dma_to_phys() and __phys_to_dma(). Unfortunately, the only apparent approach to do this is to declare and define the four sub-functions in arch/arm/mach-bcm/include/mach/memory.h, and in doing so we must move out of ARCH_MULTIPLATFORM and create brcmstb_defconfig, as we were previously using multi_v7_defconfig.
