NAME

       ioremap - map bus memory into CPU space

SYNOPSIS

       void __iomem * ioremap  (unsigned long 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.
