I think all the calypso driver code to get the Soc supported in NuttX (spi/lcd/i2c/uart/flash/sercomm/...) should eventually go Nuttx upstream and I have no problem re-licensing that under the BSD-style license.
(probably no problem for drivers, but what about l1-code)? Or are we keeping GPL and keep in sync with upstream on our own (merging could get quite ugly if that diverges too much)?
I think the L1 would be two parts: the synchronous part in the FIQ, and one 'userspace' task (might have multiple threads) for everything else.
Both should be fine as GPL, and I don't expect major headaches with keeping it in sync. The FIQ handler is completely independent from the RTOS and pre-empts it anywhere. If Nuttx right now is blocking FIQs, we should propose to change that in upstream, but still keep the L1S in our tree.
