env: Enable SPI flash env for SiFive FU540 SPI flash device on HiFive Unleashed has 32MiB Size. This patch adds SPI flash environment after U-Boot proper partition with a size of 128KiB. SPI flash partition layout(32MiB): 0 - 34 : reserved for GPT header 35 - 39 : unused 40 - 2087 : loader1 (SPL, FSBL) 2088 - 10279 : loader2 (U-Boot proper, U-Boot) 10280 - 10535 : environment 10536 - 65494 : rootfs 65528 - 65536 : distro script Note: the loader1 must start from 40th sector even though there are 6 free sectors prior since 40th sector is nearest flash sector boundary.
