> > Subject: [PATCH v3 00/11] SPL support for RISC-V
> >
> > This series adds support for SPL to RISC-V U-Boot. Images can be booted via
> > OpenSBI (FW_DYNAMIC firmware) or by directly jumping to them. In the
> > former case, OpenSBI and U-Boot proper are bundled as a FIT image and made
> > available to U-Boot SPL. Currently, only the QEMU board enables U-Boot SPL
> > with a dedicated configuration. It uses RAM as SPL boot device.
> >
> > On many RISC-V CPUs, the device tree is provided to U-Boot by the first stage
> > bootloader. This requires changes to U-Boot SPL (patches 1,
> > 2 and 3), which modify the behavior on other boards as well.
> >
> > To test this series, OpenSBI has to be compiled first. The fw_dynamic.bin
> > binary must be copied into the U-Boot root directory.
> > Alternatively, the location of the binary can be specified with the OPENSBI
> > environment variable. U-Boot can then be build as normal using the
> > configuration qemu-riscv64_spl_defconfig for 64-bit builds or
> > qemu-riscv32_spl_defconfig for 32-bit builds. The outputs from the build
> > process are the U-Boot SPL binary (spl/u-boot-spl.bin) and the U-Boot FIT
> > image (u-boot.itb) containing U-Boot proper and OpenSBI.
> >
> > U-Boot can be run in QEMU with the following command.

I have applied the patchsets to u-boot-riscv/master, thanks!
