[U-Boot] [RESEND PATCH v2 00/15] riscv: Add QEMU virt board support

[Bin Meng]

This series adds QEMU RISC-V 'virt' board target support, with the
hope of helping people easily test U-Boot on RISC-V.

Some existing RISC-V codes have been changed to make it easily to
support new targets. Some spotted coding style issues are fixed.

This series is available at u-boot-x86/riscv-working for testing.

Resend v2 to rebase on top of v2018.09 release with Tom's tree on
github, as the git.denx.de is still out of sync ...

Changes in v2:
- Change Linux kernel entry parameters' type to support 32/64 bit
- new patch to remove CSR read/write defines in encoding.h
- new patch to pass mhartid CSR value to kernel
- new patch to move do_reset() to a common place
