I think you're thinking of some other board. Cardhu is a tablet
reference platform without pluggable modules, and I believe the PMIC
mess is just due to some rework in later board revisions to solve some
under-power issues in the earlier variants. But I believe there is
some Tegra30 reference board equivalent to Whistler with all kinds of
pluggable modules, although I haven't touched one yet, and don't
recall its name.
