Platforms currently use CONFIG_SPL_DRIVERS_MISC_SUPPORT and CONFIG_MISC
to enable the MISC drivers in the SPL.
This is a bit confusing but that is not my understanding of the situation.
CONFIG_MISC enables UCLASS_MISC devices. The 'misc' drivers directory
is included always in U-Boot proper. Yes the
CONFIG_SPL_DRIVERS_MISC_SUPPORT option is for SPL only.
But in my case I want an option to enable driver-model MISC devices in
SPL/TPL. Oddly this is orthogonal to whether the drivers/misc
directory itself is included in the build.
Ok. that makes sense now.
Regards,
Simon
