boards: enabled C++ for arduino-due and udoo

[haukepetersen]

2 more towards finishing the list in #1323

[BytesGalore]

nice, alternative to #1497

[haukepetersen]

jupp, just saw #1497 -> the github search failed me. I am closing this in favor (of the original) #1497

[haukepetersen]

Hm, something is wrong with my eyes today, the udoo is missing in #1497. I could just throw out everything that is not connected to the udoo board so both PRs make sense?

[BytesGalore]

we just close #1497

[haukepetersen]

if thats ok with you. Sorry for basically overwriting your work...

[BytesGalore]

np, ACK for the arduino due part. (have no UDOO for testing)

[dangnhat]

@haukepetersen : looks good to me. I would give an ACK but I don't have the hardware to test. :(
@BytesGalore : Do you have the hardware? If yes, then I will give you the honor to test and push the merge button. :-D

[BytesGalore]

@haukepetersen @dangnhat, if someone could provide certainty on the udoo board is working it would be an honor for me to merge this PR :)

[haukepetersen]

The UDOO is hardware wise identical to the arduino-due (even the pin mappings). The difference is that it comes with a quad-core Cortex-A9 co-processor and it is slightly different to flash... So I guess you can ack without trouble?!

[BytesGalore]

@haukepetersen @dangnhat the merge message has disappeared,
So ACK and go! (just for the protocol)

[haukepetersen]

nice, I updated the list in #1323
