xDuoo X3II and X20 port
Provided by Roman Stolyarov Integration, Refactoring, and Upstreaming by Solomon Peachy 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 Change-Id: I34a674051d368efcc75d1d18c725971fe46c3eee
