Hi ansen
for new nand may recommended to add its parameters in linux/drivers/mtd/nand/nand_ids.c
and rebuild Mfg Tool firmware (files in ../firmware folder, fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot).
For rebuilding use sect.6.2 Manufacturing Tool, MFGTool attached Yocto Guide.
Use NXP Linux repository:

Best regards
igor
