This patch series includes general fixes and cleanup for RISC-V. It also adds support for booting Linux on qemu-riscv. At the moment, only single-core systems are supported. Support for multi-core systems will be added with a future patch series.
To boot Linux on qemu-riscv, Linux must be compiled into BBL as a payload. BBL must be included in a FIT image and supplied to QEMU with the -kernel parameter. Its location in memory is embedded in the device tree, which QEMU passes to u-boot. To test this, QEMU and riscv-pk (BBL) must be modified. QEMU is modified to add support for loading binary files (FIT images in this case) in addition to ELF files. riscv-pk must be modified to adjust the link address. A pull request for QEMU, which implements this, is available at [1]. A modified version of riscv-pk is available at [2].
This series applies on top of u-boot-dm/next.
Hi Lukas
Apply on top of u-boot-dm/next is ok. But apply on u-boot.git will have some conflicts.
Lukas's series is based on the VirtIO support which is currently in the u-boot-dm/master tree. I believe Simon is going to send a PR as soon as merge window opens tomorrow if everything goes well.

May I ask which tree do you want to merge into mainline ? from dm tree or riscv tree ? So the merge of patch work can go smoothly.
I think you can wait for Simon's dm tree get merged in u-boot/master, then file PR after that. Thanks!
Hi Bin
Got it.
Thanks Rick
