From 9fc4787c7a6c797db649831f86e49c4bf9780b4e Mon Sep 17 00:00:00 2001
From: Alexandre Belloni <alexandre.belloni@piout.net>

Subject: [PATCH] Change kernel address in dataflash to match u-boot's size

On at91sam platforms, u-boot grew larger than the allocated size in
dataflash, the layout was:
bootstrap  0x00000000
ubootenv   0x00004200
uboot      0x00008400
kernel     0x00042000

u-boot with the defconfig doesn't seem to fit in 0x42000 - 0x8400 =
0x39C00 bytes anymore.

Now, the layout is:
bootstrap  0x00000000
uboot      0x00004000
ubootenv   0x00084000
ubootenv2  0x00088000
kernel     0x0008C000
