No targets are enabled, but the hosted Hiby-based targets could have this
feature enabled if they weren't so buggy:
* No generic way to determine wakeup reason under Linux
* No generic way to be asynchronously notified if the alarm is
triggered when we're already awake
* Shutting down may clobber RTC wakeup (driver/etc dependent)
* Rocker's kernel's RTC driver has some 24h clock and timezone-related
issues.
So, the infrastructure is arguably useful, but the only applicable
hardware I have is pathologically brain-dead.

X3II confirmed working by forum tester, X20 is nearly identical.
This includes bootloader, main firmware, and the flash image patcher.
Eventual Todo:
* Further refactor AGPTek Rocker & xduoo hiby bootloaders
* Further refactor AGPTek Rocker & xduoo hosted platform code
