Kconfig: Set VBOOT_OPROM_MATTERS for relevant non-x86 devices
The VBOOT_OPROM_MATTERS configuration option signals to vboot that the
board can skip display initialization in the normal boot path. It's name
is a left-over from a time when this could only happen by avoiding
loading the VGA option ROM on x86 devices. Now we have other
boards that can skip their native display initialization paths too, and
the effect to vboot is the same. (Really, we should rename oprom_matters
and oprom_loaded to display_skippable and display_initialized or
something, but I don't think that's worth the amount of repositories
this would need to touch.)
The only effect this still has in today's vboot is to reboot and
explicitly request display initialization for EC software sync on
VBOOT_EC_SLOW_UPDATE devices (which we haven't had yet on ARM). Still,
the vboot flag just declares the capability (for skipping display init),
and it should be set correctly regardless of whether that actually makes
a difference on a given platform (right now). This patch updates all
boards/SoCs that have a conditional path based on
display_init_required() accordingly.
BRANCH=None
BUG=chrome-os-partner:51145
TEST=Booted Oak, confirmed that there's no notable boot time impact.
