Support Request for Arduino Portenta

The new Arduino Portenta has several UART's if using the Breakout Board but by itself it only has SerialUSB and Serial1 at D13, D14, which would be fine if it were single core but it is a dual core board. Any chance of getting AltSoftSerial working on this board. I would test any changes you suggest.

I tried #define ARDUINO_AVR_SODAQ_MBILI which would use pins 5, 6 but it errored on #define ALTSS_BASE_FREQ F_CPU

I will search a bit about that. Any opinions on if this could get running?

Just adding defines will not work. The actual code to use whatever timers that chip has needs to be written.
