I'm working on porting a set of IPQ4019 devices, Linksys WHW03 (V1 and V2), and recently a user reported a new variant of V2 with a different NAND chip, Hynix H27U4G8F2EDA-BC, which causes it not boot.
Original device V2 variant have Macronix MX30LF4G18AC, which works out of the box.
NAND chip Hynix H27U4G8F2EDA-BC seems to be successfully detected as per the boot log:
[ 1.207777] nand: device found, Manufacturer ID: 0xad, Chip ID: 0xdc
[ 1.208628] nand: Hynix H27U4G8F2EDA-BC
[ 1.215274] nand: 512 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB size: 128
but when following with nand_scan_with_ids, when calling to nand_scan_tail, NAND information, OOB, seems not to be available and it fails.

Any ideas how to trace/workaround this issue?
Note: Hynix naming scheme suggests a 4Gb SLC x8 chip, but it is detected as a 512Mb SLC.
