ARM: 6712/1: SPEAr: replace readl(), writel() with relaxed versions in uncompress.h
readl() and writel() calls the outer cache maintainance operations which are not available during Linux uncompression. This patch replaces readl() and writel() with readl_relaxed() and writel_relaxed() to avoid the link time errors.
