Portenta: How to configure for multiple Carrier boards and shields?

[KurtE]

Semi-simple question to ask, answer maybe not so simple...

For example, Portenta H7 and Cameras:

a) Suppose I have a Portenta Vision shield:

1. Version 1 has HM-01B0
2. Version 2 has HM-0360

b) Suppose I have a Mid Carrier: I can plug in any of the cameras with the Arducam pin out:
(GC2145, OV5640, OV2640, OV7670, OV7675, HM01b0, HM0360). Maybe default to GC2145.

c) Max carrier? I believe no H7 support for MIPI?

Note: the pinouts used are different between the Vision shield and the Mid Carrier.

So how should this be handled?
a) Define shields in Arduino?

Otherwise?
