[PATCH v2 0/4] QEMU spike machine support for U-Boot

[Anup Patel <apatel@ventanamicro.com>]

We can use same U-Boot binary compiled using qemu-riscv64_smode_defconfig
on QEMU virt machine and QEMU spike machine. To achieve this, we need HTIF
console support for U-Boot QEMU RISC-V board hence this series.

To test this series with latest OpenSBI, we can use the following command:
qemu-system-riscv64 -M spike -m 256M -display none -serial stdio \
-bios opensbi/build/platform/generic/firmware/fw_jump.bin -kernel \
./u-boot/u-boot.bin

These patch can be found in qemu_riscv_htif_v2 branch at:
https://github.com/avpatel/u-boot.git

Changes since v1:
 - Use ofnode_by_compatible() in PATCH3
 - Updated QEMU RISC-V documentation in PATCH4
