This patchset adds SiFive Freedom Unleashed (FU540) support to RISC-V U- Boot.
The patches are based upon latest RISC-V U-Boot tree (git://git.denx.de/u-boot-riscv.git) at commit id 91882c472d8c0aef4db699d3f2de55bf43d4ae4b
All drivers namely: SiFive PRCI, SiFive Serial, and Cadance MACB Ethernet work fine on actual SiFive Unleashed board and QEMU sifive_u machine.
Changes since v4:
- Removed #ifndef from macb_enable_clk() in PATCH7
- Updated test/dm/clk.c in PATCH10 to test fixed factor clock using sandbox
Changes since v3:
- Added patch to un-ignore arch/riscv/include/asm/arch
- Added patch to fix mrproper make target to only remove arch/*/include/asm/arch paths which are symlinks
- Added patch to have place-holder asm/arch/clk.h for RISC-V
- Removed "#ifndef CONFIG_RISCV" from macb clk API patch
Changes since v2:
- Fixed typo in PATCH3 comments
- Removed "#if" from clk_fixed_factor_ofdata_to_platdata() in PATCH7
- Added PATCH12 for SiFive FU540 README guide
Changes since v1:
- Re-ordered SoB in patches with multiple SoB
- Simplified board_get_usable_ram_top() added by PATCH3

Hi All,
Passing INITRD to Linux using bootm was not working correctly on U-Boot RISC-V. We have a fix for this which I will include in v6 of patchset.
