I don't think the dts is the right place for Linux issues.
Not sure if that's a hardware weirdness or software issue (yet).
Just checked - this goblin is there in 4.0-rc7.
I understand the issue, but still the dts is not the right place
for this comment.
Okay, got it.
I'll file a bug about this issue to the the bugzilla. However something
tells me it might not be cpuidle, but D-link. This one's sounds nasty
and it has been around since 3.16.x. How could it go unnoticed?
Unfortunately I have no other armada-370 hardware to test it.

Do you know the ECC scheme used?
Any hints on how to find it apart from dumping NAND controller
registers
from bootloader ?
From the original bootlog:
armada-nand armada-nand.0: Initialize HAL based NFC in 8bit mode with
DMA Disabled using BCH 4bit ECC
that translates into
nand-ecc-strength = <4>;
nand-ecc-step-size = <512>;
Thanks!

+ /* Hardwired into stock bootloader */
I don't get the comment above.
The stock u-boot is hacked with a 'failsafe' kernel address.
Ok, the above partition isn't passed by the bootloader on mtdparts
cmdline, i.e. that is why you call it "hardwired" ?
As far I got - stock u-boot knows nothing about partition tables and
operates just on raw NAND offsets.
Just remove the comment, actually the whole partition table is
"hacked" into the stock bootloader.
If for some reason running the 'bootcmd' fails, it reads
5MiBs from partition @ (5d00000 + 0x800) and tries to boot it.
There's no way to change this via environment, only by replacing
the bootloader.
Personally I'm more happy with a simpler partition table, but I
guess upstream should be oriented towards the stock bootloader.
Yeah, leave the original partition table. Any other, smarter
bootloader can replace it.

Thanks for the review, I'll resubmit the fixed patchset shortly.
Please disregard my [PATCH v2] messages. I've send them the moment
before
I noticed your email and review.
Please always leave the Cc-list in place.
Sorry, I had to resend that email twice. First one to you, next to the
list
and others. I'm quite new to LKML so still playing with proper email
setup.
And you should relax and leave patches there a day or two (or three).
Not everybody is reading patches immediately.
We are in no hurry, the current merge window is already closed,
the new one is 6 weeks away.
Sebastian
I only have a chance to play with the hardware at the weekend, since the
spare dns327l is at the country house, so I try to send fixes as soon as
get feedback while I can quickly test it.
