This is the legacy repository for the initial port of U-boot for the HiFive Unleashed and Microsemi expansion board. It was created by Microsemi a Microchip company for RISC-V core on HiFive Unleashed 540 device. The HiFive Unleashed Board is used for HiFive U-Boot.
Use https://github.com/sifive/freedom-u-sdk to build this version of U-boot. Eventually this version will be replaced with the upstream U-boot, which is under development at https://github.com/sifive/u-boot
