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
