On big-endian architectures like OpenRISC, sparse outputs below warnings on asm-generic/io.h. This is due to io statements like: __raw_writel(cpu_to_le32(value), PCI_IOBASE + addr); The __raw_writel() function expects native endianness, however cpu_to_le32() returns __le32. On little-endian machines these match up and there is no issue. However, on big-endian we get warnings, for IO that is defined as little-endian the mismatch is expected. The fix I propose is to __force to native endian.
