Hi,
Its just to remind sunxi_nand_spl.c is still broken. (And probably has
been for a couple releases or so).
I'm unable to fix it myself (other than reverting the mentioned commit
locally.)
Thank you,
Regards,

Hi again,
The following commit (titled "use PIO instead of DMA") apparently broke
actual reading of nand pages in SPL at least for A20:

Instead of reading page contents, non-dma (current) version just feeds

Regarding the sunxi_nand_spl.c module, I can not find any mention if it

if these modes are irrelevant in this case?
So far I'm observing that sunxi_nand_spl module refuses to load erased

Indeed, its an index, and therefore it appears SPL's detection actually
gives correct values! Nevertheless, SPL reads all zeroes from nand.

Considering addr_cycles=5, page_size=8192 accepted.
I'm almost 100% sure that correct config would be page_size=8192,

Ok, discovered a special SPL-only sunxi_nand_spl variant, added some
debugging, so the detection is visible:

Hi all,
While fighting with this A20-olinuxino nand boot process I've initially
found that some essential nand-related parameters are apparently missing
by default, preventing reasonable nand operation, so I started debugging
this gradually.
