Hi Huang,

Thanks to report this issue. :)
The root cause is that the test config doesn't enable
CONFIG_CPU_SUP_AMD.
How about below fix:
Guess you don't have a choice.
Yes, if I use test config, fam15h_power isn't chosen. :)
And if I use the "select" flag like below, fam15h_power can be built
successfully.
That is another possibility, though that isn't how CPU_SUP_AMD
is handled by its other users. Matter of philosophy, I guess.

If you say yes here you get support for processor power
information of your AMD family 15h CPU.
