Commit ceb02dcf676f ARM: delete netx machine deleted
the mach-netx machine. Then eight days later
it was resurrected by SPDX tag fixes. I think.
Taking the liberty to fix some additional debug uart
cruft.
Fixes: ceb02dcf676f ("ARM: delete netx machine")

ARM SoC folks, please apply this directly for fixes.
The machine is gone from all Kconfig etc.
I don't know if it was a person or git that decided
that the best way to add SPDX tags to deleted files
was to undelete them. If it was git I wonder if this
is the only thing it undeleted.

Odd. I wonder if this is something I did at my end, or if it happened
elsewhere through the merge path.
Anyway, thanks for noticing. I've applied this to arm/fixes now.

I think it was, I just tracked it down to commit 6ad135992e66
("Merge tag 'armsoc-drop-netx-v5.3' of
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator
into arm/soc")
which deletes a few of the netx files but leaves most of them
in place
The most likely reason for this is that you did an unclean merge
of the branch before, which left the modified files in place, and
then 'git rerere' remembered this as the resolution for the
remove/modify conflict and it did not show up at all.
The good news is that most likely nothing else suffered from the
same problem.
Arnd
