__iowrite32_copy - copy data to MMIO space, in 32-bit units : destination, in MMIO space (must be 32-bit aligned) : source (must be 32-bit aligned) : number of 32-bit quantities to copy

Copy data from kernel space to MMIO space, in units of 32 bits at a time. Order of access is not guaranteed, nor is a memory barrier performed afterwards.

__iowrite64_copy - copy data to MMIO space, in 64-bit or 32-bit units : destination, in MMIO space (must be 64-bit aligned) : source (must be 64-bit aligned) : number of 64-bit quantities to copy

Copy data from kernel space to MMIO space, in units of 32 or 64 bits at a time. Order of access is not guaranteed, nor is a memory barrier performed afterwards.
