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.
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>;
+ /* 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" ?
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
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.
