[PATCH] ARM: Push selects for TWD/SCU into machine entries

Thu Oct 4 04:50:44 EDT 2012

The TWD and SCU configs are selected by default as long as
SCORPIONMP is false and/or MCT is false. Implementing the logic
this way certainly saves lines in the Kconfig but it precludes
those machines which select SCORPIONMP or MCT from participating
in the single zImage effort because when those machines are
combined with other SMP capable machines the TWD and SCU are no
longer selected.

Push the select out to the machine entries so that we can compile
these machines together and still select the appropriate configs.

Does OMAP5 need to select TWD? I suspect not if it uses the
architected timers.
