Add the full description of the Hynix H27UBG8T2BTR-BC NAND chip in the
nand_ids table so that we can later use the NAND ECC infos and ONFI timings
mode in controller drivers.    

Still hoping to get this series [1] merged in 4.8, but if that's
not the case, I'll apply your patch.

BTW, that would be great if you could test it on your platforms.
    

It seems that Hynix-specific initialization code can't handle H27UBG8T2BTR-BC
chip:

[    0.886153] nand: Could not find valid ONFI parameter page; aborting
[    0.892665] nand: device found, Manufacturer ID: 0xad, Chip ID: 0xd7

[    0.916528] sunxi_nand: probe of 1c03000.nand failed with error -22  

Can you try this patch? It should fix the problem [1].

Yes, it fixes problem. What about ONFI parameter page? Should it be ignored?

It should be ignored: your NAND is not 'ONFI compatible', the datasheet
just says that it supports the' ONFI command set', which is not the
same :).
The trace you're seeing here is just notifying that the core failed to
detect an ONFI NAND, which is expected in your case.
