Dear Josh Wu,

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 16064 v2015.04/sama5d3xek_spiflash_defconfig_u-boot-spl.bin 16304 v2015.04/sama5d4ek_spiflash_defconfig_u-boot-spl.bin 16304 v2015.04/sama5d4_xplained_spiflash_defconfig_u-boot-spl.bin
% ls v2015.07/*spi*spl.bin -l | awk '{print $5,$(NF)}' 16136 v2015.07/at91sam9n12ek_spiflash_defconfig_u-boot-spl.bin 16300 v2015.07/at91sam9x5ek_spiflash_defconfig_u-boot-spl.bin 16664 v2015.07/sama5d3xek_spiflash_defconfig_u-boot-spl.bin 16904 v2015.07/sama5d4ek_spiflash_defconfig_u-boot-spl.bin 16904 v2015.07/sama5d4_xplained_spiflash_defconfig_u-boot-spl.bin
The gcc version is: gcc 4.7.3 (Ubuntu/Linaro 4.7.3-12ubuntu1)
