GTM stands for General-purpose Timers Module and able to generate
timer{1,2,3,4} interrupts. These timers are used by the drivers that

the Freescale USB Host controller as found in some QE and CPM
chips),
or these timers could be used as wakeup events from the CPU deep-
sleep
mode.
Things unimplemented:
1. Cascaded (32 bit) timers (1-2, 3-4).
This is straightforward to implement when needed, two timers should
be marked as "requested" and configured as appropriate.
2. Super-cascaded (64 bit) timers (1-2-3-4).
This is also straightforward to implement when needed, all timers
should be marked as "requested" and configured as appropriate.

I'd prefer something like:
depends on PPC_83xx || QUICC_ENGINE || CPM2
Btw, this is silent config, selected by the board's Kconfig
(same as QE block, for example). So "depends on" here is just
no-op, since select disregards dependencies. Still want this?
I do, its at least documentation if its not used.
