We really should not touch the generic env/Kconfig file otherwise the generic Kconfig will soon become unmaintainable. Instead put it into either board specific Kconfig, or SoC specific Kconfig. If this should be common layout for all SiFive FU540 SoCs, we should put it under arch/riscv/cpu/fu540/Kconfig Regards, Bin

SPI flash device on HiFive Unleashed has 32MiB Size. This patch add SPI flash environment after U-Boot proper partition with a size of 128KiB.
