From 0487de91427925e7c43debeb948bdf53b10ef32c Mon Sep 17 00:00:00 2001 From: Dmitri Vorobiev Date: Tue, 15 Jan 2008 00:27:46 +0300 Subject: [MIPS] Malta: Fix reading the PCI clock frequency on big-endian The JMPRS register on Malta boards keeps a 32-bit CPU-endian value. The readw() function assumes that the value it reads is a little-endian 16-bit number. Therefore, using readw() to obtain the value of the JMPRS register is a mistake. This error leads to incorrect reading of the PCI clock frequency on big-endian during board start-up. Change readw() to __raw_readl(). This was tested by injecting a call to printk() and verifying that the value of the jmpr variable was consistent with current setting of the JP4 "PCI CLK" jumper.
