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,

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

Indeed, its an index, and therefore it appears SPL's detection actually

Could some kind soul please add this id attached below?
Maybe even for 2019.01 if possible?
Otherwise nand is totally unaccessible in u-boot on some older

Ok, discovered a special SPL-only sunxi_nand_spl variant, added some

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.
