1. remove __REG macro 2. add (void __iomem *) to io_p2v macro 3. add (phys_addr_t) to io_v2p macro 4. add PKUNITY_AHB_BASE and PKUNITY_APB_BASE definitions 5. modify all PKUNITY_mmio_BASEs from physical addr to virtual addr 6. adjust prefix macro for all usage of PKUNITY_mmio_BASEs -- by advice with Arnd Bergmann Signed-off-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Reviewed-by: Arnd Bergmann <arnd@arndb.de>
