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.
I tested u-boot networking (DHCP, TFTP) on my desk with a gigE switch and it worked fine. Then, I moved it to a lab with a 100Mb switch, and DHCP doesn't work anymore.
And to be clear, neither does TFTP if setting static ipaddr/netmask/gatewayip etc.
Sound to me a bug of the GEM driver on SiFive FU540 board.
