The Linux device trees for Apple silicon devices cover now most of the hardware as u-boot's internal device trees for M1 devices. Linux has in addition device trees M2 and M1 and M2 Pro/Max/Ultra devices which were never added in u-boot. The most common use case for u-boot on Apple silicon devices does not use DTBs from u-boot but passes runtime modified device trees from an earlier boot loader (m1n1). This change regresses support for the SPI on M1 and M1 Pro/Max notebooks as SPI keyboard support is not in upstream Linux. This regression is in my opinion acceptable due to the limited use of u-boot's DTBs for these targets.
