Thomas Petazzoni c27517de00 mtd: pxa3xx_nand: make the driver work on big-endian systems ... commit b7e460624f upstream. The pxa3xx_nand driver currently uses __raw_writel() and __raw_readl() to access I/O registers. However, those functions do not do any endianness swapping, which means that they won't work when the CPU runs in big-endian but the I/O registers are little endian, which is the common situation for ARM systems running big endian. Since __raw_writel() and __raw_readl() do not include any memory barriers and the pxa3xx_nand driver can only be compiled for ARM platforms, the closest I/o accessors functions that do endianess swapping are writel_relaxed() and readl_relaxed(). This patch has been verified to work on Armada XP GP: without the patch, the NAND is not detected when the kernel runs big endian while it is properly detected when the kernel runs little endian. With the patch applied, the NAND is properly detected in both situations (little and big endian).
