@AnttiKauppila @davidsaada Can you please look at the failures?

From the logs, some targets fail to build for these 2 additions. I can see that lorawan example in some cases have a problem with pin configuration.

for nvstore, some undefined needed symbols

[davidsaada]

Fixed the NVStore issue.

[AnttiKauppila]

We indeed have some wrong PIN mappings. I am currently running our tests and when those are passing, I will provide a fix for this

[AnttiKauppila]

This should fix the PIN issues:

@AnttiKauppila Fix helped, there are different failures now. Small devices have a problem and some even bigger ( k82f should have enough, might be a problem with linker script there?)

[AnttiKauppila]

I have provided another fixes by disabling example app in devices not supporting LoRa.

There is still one issue and it cannot be fixed by our application.
Our radios (Sx1272 and 1276) are using PinMode.PullUp enumeration and in target MIMXRT1050_EVK it is not available. I checked PinNames.h for this target and there are 3 different PullUps available: PullUp_47K, PullUp_100K and PullUp_22K.

I think this is an issue in the PinMode enumeration in "mbed-os/targets/TARGET_NXP/TARGET_MCUXpresso_MCUS/TARGET_MIMXRT1050/TARGET_EVK/PinNames.h", because for example DigitalIn.h documents this usage:
/** Set the input pin mode
*
* @param pull PullUp, PullDown, PullNone, OpenDrain
*/
void mode(PinMode pull);

@0xc0170, @adbridge Do you know who is responsible of this target?

[0xc0170]

I'll check that failure, and can propose a fix.

PR is now in master! Rebase needed to pull it in.

Closing since duplicate has now been merged and RC2 is now a thing.
