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
Anup Patel (4): serial: Add RISC-V HTIF console driver riscv: qemu: Enable HTIF console support riscv: qemu: Implement is_flash_available() for MTD NOR doc: qemu-riscv: Update documentation for QEMU spike machine
Can this series be considered for the upcoming v2022.04 release ?
Best Regards, Anup
