[U-Boot] [PATCH v2 00/11] SiFive FU540 Support

[Anup Patel]

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 v1:
 - Re-ordered SoB in patches with multiple SoB
 - Simplified board_get_usable_ram_top() added by PATCH3

Anup Patel (7):
  riscv: Rename cpu/qemu to cpu/generic
  riscv: Add asm/dma-mapping.h for DMA mappings
  riscv: generic: Ensure that U-Boot runs within 4GB for 64bit systems
  net: macb: Fix clk API usage for RISC-V systems
  clk: Add SiFive FU540 PRCI clock driver
  clk: Add fixed-factor clock driver
  riscv: Add SiFive FU540 board support

Atish Patra (4):
  net: macb: Fix GEM hardware detection
  drivers: serial_sifive: Fix baud rate calculation
  drivers: serial_sifive: Skip baudrate config if no input clock
  cpu: Bind timer driver for boot hart
