Hi Alistair,
As I see, we are moving on to remove TARGET_RISCV64 macro.
I have some questions:
1) Which tcg op should use when translate an instruction for 32bit cpu.
The tcg_*_i64, tcg_*_i32 or tcg_*_tl?
I see some API such as gen_get_gpr that are using the tcg_*_tl. But I am
not sure if

Hello,
Posting these for early review now. I plan to rebase on the next VOF
patch that hopefully fixes those points that I had to circumvent in
patch 1 for now. I've reported these before but now all of those
Linux uses RTAS functions to access PCI devices so we need to provide
these with VOF. Implement some of the most important functions to
allow booting Linux with VOF. With this the board is now usable
without a binary ROM image and we can enable it by default as other
boards.
