[PATCH 0/1] EmbeddedPkg/Library: Add VirtualRealTimeClockLib

[Pete Batard <pete@akeo.ie>]

This is work, which was requested as part of the Raspberry Pi 3 platform
integration, is designed to remove the need to provide various custom RTC
implementations for platforms that don't have a real RTC.

The library, which is arch-agnostic (through usage of the perf counter) is
designed to emulate as much as it can as of a hardware backed RTC, including
time zones, daylight savings and nanosecond precision.

Note that, since it relies on automatically setting of the epoch value at
compilation-time, it is currently only meant to support gcc based build
environments and relies on UNIX-like shells that provide a 'date' command.
For other environments, the compilation is designed to break in a manner that
will direct the builder to contact the edk2 mailing list, so that we can look
at adding support for their setup.

Regards,

/Pete
