Gabor Juhos d6cb5215a9 ar71xx: WNR2200: fix mounting root fs problem 
Solves ticket #14356 <https://dev.openwrt.org/ticket/14356>

Without this patch, UART output will show only 4 partitions:
  [    0.740000] 4 cmdlinepart partitions found on MTD device spi0.0
  [    0.750000] Creating 4 MTD partitions on "spi0.0":
  [    0.750000] 0x000000000000-0x000000050000 : "u-boot"
  [    0.760000] 0x000000050000-0x000000070000 : "u-boot-env"
  [    0.770000] 0x000000070000-0x0000007f0000 : "firmware"
  [    0.790000] 0x0000007f0000-0x000000800000 : "art"
and then linux complains :VFS: Cannot open root device "(null)"

With this patch, UART out will show 7 partitions:
  [    0.740000] 4 cmdlinepart partitions found on MTD device spi0.0
  [    0.750000] Creating 4 MTD partitions on "spi0.0":

  [    0.780000] 0x000000050000-0x00000014b440 : "kernel"
  [    0.790000] mtd: partition "kernel" must either start or end on erase block boundary or be smaller than an erase block -- forcing read-only

  [    0.810000] mtd: partition "rootfs" must either start or end on erase block boundary or be smaller than an erase block -- forcing read-only

  [    0.840000] 0x0000007f0000-0x000000800000 : "art"

This patch is tested against r39502 of trunk.

README 

This is the buildsystem for the OpenWrt Linux distribution.

Please use "make menuconfig" to configure your appreciated
configuration for the toolchain and firmware.

You need to have installed gcc, binutils, bzip2, flex, python, perl
make, find, grep, diff, unzip, gawk, getopt, libz-dev and libc headers.

Run "./scripts/feeds update -a" to get all the latest package definitions
defined in feeds.conf / feeds.conf.default respectively
and "./scripts/feeds install -a" to install symlinks of all of them into
package/feeds/.

Use "make menuconfig" to configure your image.

Simply running "make" will build your firmware.
It will download all sources, build the cross-compile toolchain, 
the kernel and all choosen applications.

You can use "scripts/flashing/flash.sh" for remotely updating your embedded
system via tftp.

The OpenWrt system is documented in docs/. You will need a LaTeX distribution
and the tex4ht package to build the documentation. Type "make -C docs/" to build it.

To build your own firmware you need to have access to a Linux, BSD or MacOSX system
(case-sensitive filesystem required). Cygwin will not be supported because of
the lack of case sensitiveness in the file system.
