[PATCH 1/6] ARM: dts: am335x-phycore-som: Update NAND partition table

[Teresa Remmet]

To improve NAND safety we updated the partition layout.
Added barebox backup partition and removed kernel and oftree
partition. They are kept in ubi now.

What about the users with earlier partition tables?

Please read about "flag day" changes, typically they are not
acceptable.

Adding Brian and Adam to Cc. Can you guys come up with some
solution on this?

I'm suggesting we leave the kernel nodes empty and let u-boot
populate them, so maybe you guys can discuss this on the related
lists.

The rest of the series looks fine to me so applying it into
omap-for-v4.11/dt.

Cheers,

Tony

I don't have much context for this thread, and no I don't plan to solve
your problems for you. But I can provide tips!

That's an option. I've worked with platforms that did something like
this, and that's really one of the only ways you can handle putting
partition information in the device tree. You're really hamstringing
yourself when you put all the partition information in the device tree.
And it's just dumb once that gets codified in the kernel source tree.

The best solution would be to try to migrate away from static device
tree representations of partition info entirely. UBI volumes are best
where possible. If not, then some other kind of on-flash data structures
(along the lines of a GPT) with a corresponding MTD partition parser is
an OK alternative. Unfortunately, there isn't any good standard format
for this on MTD, so it's typically all custom -- and so people use the
easiest approach: device tree. And it's even more difficult with NAND,
which has reliability problems, especially with static data (e.g., read
disturb).

Anyway, the parser solution is helpful only if one can properly fix the
"flag day" first. And it requires a little bit more work to be generally
useful; I posted some work for this over a year ago, but bikeshedding
brought it down.

In our case the bootloader does pass the partition table to the kernel.
So it gets overwritten anyway. This was just more for backup, 
if someone uses a different bootloader. But I'm fine with removing the
nand partition table completely from the kernel device tree.
Same with the SPI nor partition table.

I will send patches for this.

Teresa

Tony - I tested leaving the partition info as-is with the updates from
the bootloader and it works.  Would you prefer that I match Brian and
remove the partition table completely, or should I just leave my board
alone?

I am good either way.

OK. How about let's remove the partitions from kernel for v4.11 as
clean-up then for cases where the bootloader might change them?

Ah, well if these are essentially just a backup, then why do they need
changed at all? To be more precise about my "dumb" statement: it seems
unwise to assume that all systems using a particular board will have the
same partition layout. So *relying* on the in-kernel DTS(I) files to
have a universal partition layout would likely cause problems.

I don't have much problem with keeping a sample layout there as a
backup, if you find it useful. But it seems like it will be hard to
argue that you can ever change it in the future.

Anyway, the ofpart mechanism is there, and it's fine to use it, but it's
up to you to understand the implications and manage the backwards
compatibility problems :)

I don't have much stake in this but...if there were any systems using
the backup layout (i.e., the in-kernel partition layout), wouldn't that
break them? Is there a problem with just leaving them alone?

Yeah I guess it depends on the device and it's bootloader versions.
