Guys,
If you're going to introduce a dependency on some infrastructure which
you absolutely require for booting, then _please_ ensure that the
configuration system is updated such that pre-existing kernel
configurations continue to work.
Don't leave it such that the infrastructure ends up returning -ENOSYS,
which then filters down into your SoC specific code, and aborts the
initialisation of critical infrastructure, leaving you with a totally
silent boot failure.
In this case, it's the addition of syscon to OMAP internals,
specifically in omap_control_init().
This is explicitly targetted at OMAP people, who have wasted much of
my day today investigating why their platforms no longer boot in DT
mode.
Thanks.
