NAME
       ioremap_nocache - map bus memory into CPU space

SYNOPSIS
       void __iomem * ioremap_nocache(resource_size_t offset, unsigned long size);

ARGUMENTS
       offset
           bus address of the memory

       size
           size of the resource to map

DESCRIPTION
       ioremap performs a platform specific sequence of operations to make bus memory CPU
       accessible via the readb/readw/readl/writeb/ writew/writel functions and the other mmio
       helpers. The returned address is not guaranteed to be usable directly as a virtual
       address.

       If the area you are trying to map is a PCI BAR you should have a look at pci_iomap.
