This patchset adds SiFive Freedom Unleashed (FU540) support to RISC-V U-Boot.
The patches are based upon latest U-Boot source tree (git://git.denx.de/u-boot.git) at commit id dbe70c7d4e3d5c705a98d82952e05a591efd0683
All drivers namely: SiFive PRCI, SiFive Serial, and Cadance MACB Ethernet work fine on actual SiFive Unleashed board and QEMU sifive_u machine.
Looks like the MACB driver cannot find the correct MAC address. That makes it rather awkward for network boot.
Warning: ethernet@10090000 (eth0) using random MAC address - 0e:14:15:06:ae:e4
This is because we don't have place to put U-Boot environment variables as of now on Unleashed board. This will be solved once we have SPI driver and SPI_MMC driver for Unleased board.
In future, we will be saving "ethaddr" environment variable on SPI_MMC so U-Boot will pick MAC address at boot-time from SPI_MMC. Once this is achieved, the above warning will go away.
How is the MAC determined in Linux?
