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.
