On at91sam platforms, u-boot grew larger than the allocated size in dataflash, the layout was: bootstrap 0x00000000 ubootenv 0x00004200 uboot 0x00008400 kernel 0x00042000 fs 0x00252000 u-boot with the defconfig doesn't seem to fit in 0x42000 - 0x8400 = 0x39C00 bytes anymore. Now, the layout is: bootstrap 0x00000000 ubootenv 0x00004200 uboot 0x00008400 kernel 0x00084000 fs 0x00294000 Signed-off-by: Alexandre Belloni <alexandre.belloni@piout.net> Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
