*Dovetail, CXP and EVL update

Xenomai on Dovetail
- Several crashing issue are being fixed.
- Adding test tool from EVL to Xenomai. Extending latency test for GPIO.
- X86 code ready within several days.
- Then switch to ARM/ARM64 porting.
- PowerPC is not supported by Dovetail. Community can chime in as needed.
- Early delivery in Feb.

CXP
- The idea is to simplify the project
  Not provide more than what we can sustain, and
  Not provide no used features
- Still lack of feedback in community.

EVL
- Support POSIX on EVL core
- Plan to port RTDM to EVL
- Concern on drivers
- RT Network stack shall leverage as much the native stack rather than 
creating everything from the ground up.


*Customer feedback

Some PRC Xenomai customers feedback:
- Generally OK to port to POSIX API if no functionality and performance 
downgrade;
- Some customer is using Alchemy API "rt_task_*" since Xenomai 2. The 
customer is ok to port to POSIX API;
- RTDM drivers used for GPIO, SPI, Serial, PCIe Can card, IgH EtherCAT, etc. 


Next community call: Feb 10, 2021


Thanks,
Rick
