riscv configuration cannot work on 32bit OS about riscv-linux

[terpstra]

What version of risc-v tools are you using and which kernel version? It is very unlikely that error is caused by your host CPU being 32-bits. The file being compiled in your example was a RISC-V file.

@terpstra This appears to have been an attempt to compile the kernel for riscv32.

This has been fixed.

Check this emulator:

RISC-V 32-Bit is finally working with the new privilege spec.

Very cool! I see you copied spike's device tree string, but changed mmu-type to sv32. Does this mean spike now also can run linux 32-bit? Did you have to change much in the kernel to handle sv32? Are those changes merged?

Following tree should compile out of the box.

Today, I have also commented on the necessary changes for spike/pk here: #61

Not much to do I think. It is just the console handling.
