Besides those OMAP-specific packages, there are also other packages
that could depend on CPU-specific features.
For example, some video decoders have specific code to use NEON
instructions, but those instructions are not available on Cortex-A8
cores for example.
Should we go all the way down to specifying the particular CPU the user
is going to use (OMAP3, OMAP4, etc.) and then select the appropriate
mtune/march according to this, show/hide packages according to this,
and tune specifically some packages according to this ?
