From 083522d76662cda71328df1f3d75e5a9057c7c9f Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Fri, 15 Dec 2006 06:54:08 +1100 Subject: USB: Implement support for EHCI with big endian MMIO This patch implements supports for EHCI controllers whose MMIO registers are big endian and enables that functionality for the Toshiba SCC chip. It does _not_ add support for big endian in-memory data structures as this is not needed for that chip and I hope it will never be. The guts of the patch are to convert readl(...) to ehci_readl(ehci, ...) and similarly for register writes.
