It's already supported in current linux/master:

$ git describe origin/master
v5.16-rc1-3-g8ab774587903

Sorry I don't understand, could you expand on the proper way to handle
the above configuration? AFAICS, several imx8m boards follow this same
pattern:

$ git grep -l CONFIG_SPL_BUILD -- include/configs/imx8m*
include/configs/imx8mm-cl-iot-gate.h
include/configs/imx8mm_beacon.h
include/configs/imx8mm_evk.h
include/configs/imx8mm_icore_mx8mm.h
include/configs/imx8mm_venice.h
include/configs/imx8mn_beacon.h
include/configs/imx8mn_evk.h
include/configs/imx8mp_evk.h
include/configs/imx8mq_cm.h
include/configs/imx8mq_evk.h
include/configs/imx8mq_phanbell.h
