As sama5 board has 32k sram size, so the at91bootstrap and spl for sama5
boards is bigger than 16k (0x4000). That will overlap the U-Boot
environment. So I move environment to 0x6000. And reduce its size as
well.
Following shows the size of the spl binaries (v2015.04 vs v2015.07):
% ls v2015.04/*spi*spl.bin -l | awk '{print $5,$(NF)}'
15540 v2015.04/at91sam9n12ek_spiflash_defconfig_u-boot-spl.bin
15704 v2015.04/at91sam9x5ek_spiflash_defconfig_u-boot-spl.bin
