PowerPC progress

[Simon Glass]

Hi Tom,

I do see some progress with PowerPC migration but it seems to be very
behind. I notice that it is often PowerPC code that gets in the way or
refactoring and cleaning up.

Could we get a progress update on this please? I cc'd the maintainers
that are mentioned in the code. I do worry at the effort it is taking
to keep all this old code in the tree.

Regards,
Simon

Which particular area are you worried about currently?  I believe we've
had another good sized removal of PowerPC platforms and everything
that's left is what's wanted and being further migrated and updated.

Actually we're just discussing with a customer to bring MPC82xx back
into mainline (and maintain it for another 5...7 years ....

It's hard to be specific, but these come to mind:

- Loads of CONFIG options still not in Kconfig
- asm/u-boot seems to include a huge array of headers
- code style not up-to-date - e.g. printf (xxx) instead of printf(xxx)
- lots of migration warnings

I'm pleased things are moving forward but would like to know if there
are timelines.

Regards,
Simon

I still have a few old boards, I?ll see what is still functional and jump in to assist.
If we want to revive 82xx, as Wolfgang mentioned, I can probably do that as well.

The list above is helpful to get started.

Thanks.

I am working on NXP powerpc platforms
We are working on a list (P1010, P1020, P2020, P2041, P3041, P4080, P5040, T1024, T1042, T2080, T4240, MPC8548CDS) for which we are ensuring DM migration and will remove the support of other platform which NXP no longer intend to maintain. 
Please expect the series of those patches by this month end.

Priyanka
