Hello Ramon,
a major benefit of the driver model is that drivers are selected via the
device tree.
In Linux the driver is in drivers/soc. Wouldn't it make sense to create
a minimal uclass for platform devices in drivers/soc on U-Boot?
drivers/ram/ram-uclass.c shows what a minimal uclass looks like.
The identifier has to be added in include/dm/uclass-id.h.
Best regards
Heinrich
