Detailed Description

Low-level CPU ID peripheral driver.

Provides access the CPU's serial number

(Low-) Power Implications

The implementation should make sure, that calling cpuid_get() does not introduce any long-term power usage penalties. If e.g. some peripheral has to be powered on for the CPU ID to be read, the implementation should take care to disable the peripheral again after the read is finished.
