The kernel raw nand API has seen some significant changes recently. It looks like the kernel marvell_nand driver relies on newer API. I'm not sure how easy would be syncing the drivers to a degree that makes porting of changes trivial. It would probably require many other changes in generic U-Boot raw NAND code. Maybe Miquel can shed some light on that. Unfortunately, the U-Boot MAINTAINERS NAND FLASH entry is marked "Orphaned (Since 2018-07)". baruch >> Baruch Siach (2): >> arm: dts: armada-cp110-master: update nand-controller >> mtd: pxa3xx_nand: remove dead code >> >> Shmuel Hazan (3): >> arm: dts: armada-cp110-slave: add missing cps_nand >> mtd: pxa3xx_nand: port to use driver model >> mtd: nand: pxa3xx: enable NAND controller if the SoC needs it >> >> arch/arm/dts/armada-cp110-master.dtsi | 15 ++- >> arch/arm/dts/armada-cp110-slave.dtsi | 16 +++ >> drivers/mtd/nand/raw/Kconfig | 2 + >> drivers/mtd/nand/raw/pxa3xx_nand.c | 179 ++++++++++++++------------ >> 4 files changed, 124 insertions(+), 88 deletions(-) >> >> -- >> 2.28.0 >> -- ~. .~ Tk Open Systems =}------------------------------------------------ooO--U--Ooo------------{= - bar...@tkos.co.il - tel: +972.52.368.4656, http://www.tkos.co.il -
