Since all the series is reviewed/tested and Igor asked to amend a fixup
but we are having hard time to figure if we understand Igor request
correctly, I thought it would be easier for him to review this way, then
for Richard to squash the patches and send the pull request.
Is it confuse/bad practice?
In the cover I wrote:
If Igor aggrees with the fixup patches, Richard, can you squash
them and send a pull request? (without the last patch, which is
expected to go via Eduardo's tree, but since it is helpful for
testing this series, I included it).

I've explicitly asked for merging if I'm not mistaken.
> Is it confuse/bad practice?
it's confusing at least for me, since I have to review broken patch and fix ups
on top doing merge in my head and still won't be sure if I've missed
something in process on not.
(Fix ups are fine for trivial change that affect only one patch,
which isn't case here)
Please respin.

This line belongs to the previous !fixup patch, but it is a fixup anyway...

We were eliding all zero indexes. It is only ld==0 that does
not have an index in the instruction. This also allows us to
avoid breaking the final print into multiple pieces.

This has consistency with prt_ri(). It loads all data before
beginning output. It uses exactly one call to prt() to emit
the full instruction.

There are so many different forms of each RX instruction
that it will be very useful to be able to look at the bytes
to see on which path a bug may lie.

While the VIRT machine can use different microcontrollers,
the RX62N microcontroller is tied to the RX62N CPU core.

Add two tests for the rx-virt machine, based on the recommended test
setup from Yoshinori Sato:
https://lists.gnu.org/archive/html/qemu-devel/2019-05/msg03586.html
- U-Boot prompt
- Linux kernel with Sash shell
These are very quick tests:
