ath79: mikrotik: update nand-rb4xx driver
This updates the NAND driver for MikroTik RB4XX series to work with kernel 5.10, similarly to the ar934x-nand driver (fb64e2c3
). Support for kernel 5.10 was added to all ath79 subtargets except for the mikrotik one by commitd6b785d
, since patch 920-mikrotik-rb4xx.patch needed to be reworked. Later, commitf8512661
enabled kernel 5.10 for the mikrotik subtarget with the nand-rb4xx driver still pending, which is updated and added back by this patch. Compile-tested only. Signed-off-by: Roger Pueyo Centelles <roger.pueyo@guifi.net>
