[U-Boot] [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.

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

Bin Meng (15):
  riscv: kconfig: Normalize architecture name spelling
  riscv: Remove setup.h
  riscv: bootm: Correct the 1st kernel argument to hart id
  riscv: Remove mach type
  riscv: Move the linker script to the CPU root directory
  riscv: Fix coding style issues in the linker script
  riscv: Explicitly pass -march and -mabi to the compiler
  riscv: Add a helper routine to print CPU information
  riscv: Remove CSR read/write defines in encoding.h
  riscv: bootm: Pass mhartid CSR value to kernel
  riscv: Make start.S available for all targets
  riscv: ae350: Clean up mixed tabs and spaces in the dts
  riscv: kconfig: Select DM and OF_CONTROL
  riscv: Add QEMU virt board support
  riscv: Move do_reset() to a common place
