[U-Boot] [PATCH v2 0/2] SiFive UART support

[Anup Patel]

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.
