Subject: [PATCH] powerpc/qixis: add clock measurement registers
QIXIS includes frequency measurement functions for each major processor
clock input. After reset (and after clocks are stable), QIXIS measures
the clocks against a reference frequency and stores the results in
CLK_FREQ registers. A base register supplies a multiplier which allows
directly obtaining the measured value, without requiring knowledge of
the target system or QIXIS core frequency.
