target/linux/brcm63xx/patches-2.6.32/012-mips_add_readl_writel_be_accessors.patch

   1 MIPS currently lacks the readl_be and writel_be accessors
   2 which are required by BCM63xx for OHCI and EHCI support.
   3 Let's define them globally for MIPS. This also fixes the
   4 compilation of the bcm63xx defconfig against USB.
