Allocating a fixed size info buffer before nand_scan_ident and attach it
on the struct meson_nfc; Or considering not use dma for reading data
less than 8 bytes. Both can reduce kmalloc and kfree calling. Thanks.
both suggestions sound reasonable.
however, I will search for the root cause of the unaligned address
first before changing the Meson NFC driver.
That is good. And i will implement one of both mentioned above soon.

miss mtd_set_ooblayout(mtd, &meson_ooblayout_ops) on function
meson_nand_attach_chip.
thank you for the suggestion. I didn't have time to test this on my
board yet but I'll let you know about my results during the weekend.
Does the missing mtd_set_ooblayout() call also affect GXL or AXG boards?
Yes. I deleted it unintentionally.
