Yong,
I get the following errors if I try to compile this with the Linaro toolchain.

struct mx51_cpu_op ?
IIUC, other I.MX SoCs use different 'variables' so this struct is
SoC-specific.

Get rid of all members of struct cpu_op except cpu_rate for now. We can
re-add it later.
Also, I wonder if this struct and the external declaration should be moved
out to plat/mxc_cpufreq.h
