Re: [PATCH 20/20] bootwrapper: Add fsl_get_immr(), mpc885_get_clock(), and pq2_get_clocks().

fsl_get_immr() is equivalent to the kernel's get_immrbase() function.

I notice that this function assumes that P==V.  Is that true for all
relevant platforms at this point?

mpc885_get_clock() transforms a crystal frequency into a system frequency
according to the PLL register settings.

pq2_get_clocks() does the same as the above for the PowerQUICC II,
except that it produces several different clocks.

I'd prefer if these functions worked analagously to the
ibm440gp_fixup_clocks() function in ebony.c and fixed up the clock
values in the device tree directly, rather than returning them (where
the caller will presumably poke them into the device tree).
