Hi,
  Any more comments on this patch?
I'm not sure if enabling kernel options by default is a good thing.
Somehow I remember that enabling things by default is not looked kindly
at. Shouldn't they be enabled in the arch/arm/configs config file, if
they are wanted?

Tony, do you have opinnion on this? Should DSS features be enabled by
default in the Kconfig files, or only in the board config file?
The best thing would be to have DSS y if ARCH_OMAP2PLUS or similar,
then have all the features built in and pass the configuration options
in platform_data. That still allows disabling certain features with
Kconfig if needed for memory consumption etc. But the omap2plus_defconfig
should "just work" on all the boards.
Personally, I'd much rather see DSS core and optional features default
to being built as a module.

Other than a splash screen, there's no reason DSS is needed for a
minimal boot.
Sure a module would be even better. My point is that the selection of
all the features should be enabled by default and the board options come
from platform_data.
