map bus memory into CPU space

void __iomem *ioremap_nocache(resource_size_t phys_addr, unsigned long size)

メモ

  • ioremap_nocache 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.
