Add MAMBAF405 target

[shellixyz]

Closes #4262

[dentex]

@shellixyz Hi. If i'm not missing something, it's the same FC as this one: #4464

[shellixyz]

@dentex ehm ok maybe yes. The MambaF405 doesn't need anything to be changed compared to the FF4OSD target ? I don't have one I can't check anything. The analog channels are different between the two target files. Also the FF4OSD have a SS configured. And maybe other stuff different I didn't check everything.

[dentex]

@shellixyz Yes, there are small differences between the two target files we have. Incidentally, for the one that has been already merged (32ca1a9), a couple of pins must be swapped, as per this comment: #4262 (comment)
I mean, the BF's target for the MambaF405 is the FURYF4OSD (that has some switches for other flavours - but not the one in iNav): so I think we are pushing two targets for the same FC.

[shellixyz]

OK so it would just need to be a variant of the FF4OSD then

[dentex]

In BF it's like this.
Please note that the OSD variant is the Mamba.
Our target isn't set for the FURYF4 (non-OSD) also... So we basically need to only decide how to name the target and resolve those tiny differences... I flashed both and nothing changed... (apart from the two pins I was referencing above).

@dentex Ok, should be good now

[sergeyprokofev]

For Smart Audio if not used PPM. Verified by.
#define USE_SOFTSERIAL1
#define SOFTSERIAL_1_RX_PIN PA1 // or NONE
#define SOFTSERIAL_1_TX_PIN PC9 // FOR Smart Audio if not used PPM
#define SERIAL_PORT_COUNT 5

and (or am i wrong?)
#define MAX_PWM_OUTPUT_PORTS 6 // 4 - morots, softserial, led strip

@shellixyz is this ready?

[shellixyz]

Yes it should be. I don't have a board to test though

[gsixx8]

@shellixyz I have the F4 Mamba and am trying to get it working correctly with INAV. I would be interested in testing out the version you all are referencing.

I will test fport tonight....you have take inverted or non inverted smartport with your r9mm??

I just tried to build mambaf405 from development and SBUS and softserial on PPM pad does not work. I tried the build (zip file above) and it works but that build is from an older code base. Did also try FuryF4OSD and SBUS does not work with that one either.
