Status update

[Nick Hudson <nick.hudson%gmx.co.uk@localhost>]

Hi,

With a bunch of help from Simon Burge we've managed to get the RISC-V 
port to running /rescue/sh in qemu for RV64.

nick@thinkbook:~/emulators/netbsd-riscv$ sh run.sh
WARNING: Image format was not specified for 'riscv64.img' and probing guessed raw.
         Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.
