Rob, I assume you'll do a patch for this one?

The patch below fixes the 8250 related issue by removing the
selects from Kconfig and adding them to omap2plus_defconfig.

Felipe, can you take a look at removing the MUSB selects from Kconfig?
You might be able to just have MUSB depends on TWL if omap.

Subject: [PATCH] ARM: OMAP2+: Fix unmet direct dependencies for zoom for 8250 serial

We should not select drivers from kconfig as they should by default
be optional. Otherwise we'll be chasing broken dependencies forever:

warning: (MACH_OMAP_ZOOM2 && MACH_OMAP_ZOOM3 && MWAVE) selects SERIAL_8250
which has unmet direct dependencies (TTY && HAS_IOMEM && GENERIC_HARDIRQS)

Fix the issue by removing the selects for zoom and add them to
omap2plus_defconfig.
