I've also thought about such workaround, but debugging bootloader/kernel comes in question too. I'd like to use UBIFS and as far as I can see such WiSoCs have support for really ancient U-Boot, that doesn't provide UBI support. The situation has changed for AR9331, because it was included into Barebox tree, but for mt7620 I could find nothing. Do you have any experience using UBIFS with SPI flashes?
