The i.MX cpufreq implementation uses the CPU_FREQ_TABLE helpers,
so it needs to select that code to be built. This problem has
apparently existed since the i.MX cpufreq code was first merged
in v3.6.37.
Building IMX without CPU_FREQ_TABLE results in:
arch/arm/plat-mxc/built-in.o: In function `mxc_cpufreq_exit':
arch/arm/plat-mxc/cpufreq.c:173: undefined reference to
`cpufreq_frequency_table_put_attr'
arch/arm/plat-mxc/built-in.o: In function `mxc_set_target':
arch/arm/plat-mxc/cpufreq.c:84: undefined reference to
`cpufreq_frequency_table_target'
arch/arm/plat-mxc/built-in.o: In function `mxc_verify_speed':
arch/arm/plat-mxc/cpufreq.c:65: undefined reference to
`cpufreq_frequency_table_verify'
arch/arm/plat-mxc/built-in.o: In function `mxc_cpufreq_init':
arch/arm/plat-mxc/cpufreq.c:154: undefined reference to
`cpufreq_frequency_table_cpuinfo'
arch/arm/plat-mxc/cpufreq.c:162: undefined reference to
`cpufreq_frequency_table_get_attr'
