This patch adds booti support for RISC-V Linux kernel. The existing bootm method will also continue to work as it is.

"arm64/riscv" is distracting. If I am on RISC-V I cannot boot an ARM64 image here. Remove the reference to the architecture, please.
Hello,
I'm not sure about the last point - ISTR (please correct me if my memory betrays me here) that an arm64 U-Boot can in principle be used to boot either an arm64 or an armv7 kernel, but the commands are different in those cases (booti for an arm64 "Image" format kernel and bootz for an armv7 "zImage" format kernel), so having the information which kernel format is supported by the respective commands appears useful to me. If the arm64 kernel image format would have a distinctive name (like "zImage" on armv7 or "bzImage" on x86) that would be less problematic, but with the confusion potential of "boot a Linux Image" (as in the arm64/riscv-specific "Image" format) vs "boot a Linux image" (as in generally some form of kernel image), I think explicitly mentioning the supported architectures makes sense.
In this case you have to ensure that only the *supported* architectures are mentioned. RISC-V is not supported on ARM64.
Best regards
