This patchset adds SiFive UART driver for SiFive UART found on SiFive boards.
The driver is tested on QEMU sifive_u machine. In fact, with this patchset same U-Boot binary boots on QEMU virt machine and QEMU sifive_u machine in both M-mode and S-mode.
The patches are based upon latest RISC-V UBoot tree (git://git.denx.de/u-boot-riscv.git) at commit id 48cbf6246052de10d35b616b5efb2f783904a49d
Changes since v1:
- Fixed copyright header in SiFive UART driver
- Imply SIFIVE_SERIAL for QEMU emulation instead of enabling it in defconfigs.

Hi Rick,
The required QEMU fix has been submitted by Alistair Francis on QEMU mailing list. (QEMU PATCH subject "sifive_u: Set 'clock-frequency' DT property for SiFive UART")
Can you please consider this series for U-Boot v2019.01?
Thanks, Anup
