Hi Oliver,

I get errors when I build the board (some configs must be in defconfig 
instead of header):

+(imx8qm_dmsse20a1) Error: You must add new CONFIG options using Kconfig
+(imx8qm_dmsse20a1) The following new ad-hoc CONFIG options were detected:
+(imx8qm_dmsse20a1) CONFIG_ETHPRIME1
+(imx8qm_dmsse20a1) CONFIG_FEC1_ENET_DEV
+(imx8qm_dmsse20a1) CONFIG_FEC1_MXC_PHYADDR
+(imx8qm_dmsse20a1) CONFIG_FEC2_ENET_DEV
+(imx8qm_dmsse20a1) CONFIG_FEC2_MXC_PHYADDR
+(imx8qm_dmsse20a1) CONFIG_IMX_SMMU
+(imx8qm_dms

Can you check this, please ?

Best regards,
Stefano Babic
