Hi all, hi Greg,

These patches are an updated version from the ones I posted some time ago.
They give the FEC ethernet driver a facelift and turn it into a
platform_device driver. The Coldfire cores are still supported through
legacy ifdefs. The platform driver support has been tested on a
Freescale i.MX27 SoC.

Sascha

The following changes since commit 5ee810072175042775e39bdd3eaaa68884c27805:
  Linus Torvalds (1):
        Fix "multiple definition of `debugfs_create_size_t'"

are available in the git repository at:

  git://git.pengutronix.de/git/imx/linux-2.6.git fec-pu

Sascha Hauer (9):
      fec: remove unused #else branches
      fec: remove empty functions
      fec: use linux/*.h instead of asm/*.h
      fec: do not use memcpy on physical addresses
      fec: use dma_alloc_coherent for descriptor ring
      fec: Fix KS8721BL_ICSR phy register offset
      fec: replace flush_dcache_range with dma_sync_single
      fec: Add support for Freescale MX27
      FEC: Turn FEC driver into platform device driver

Subject: [PATCH] fec: remove unused #else branches
Date: Tuesday, January 27, 2009 - 3:24 am

From: Sascha Hauer <s.hauer@pengutronix.de>

The #else branches throughout this driver belong to a PowerPC 8xx for
which this driver is not used.

There are some architecture specific functions which are all
empty. Remove them.
