Lots of work to do a full u-boot replacement, yes. But a basic one using
existing NuttX stuff such as RNDIS, dfu, mtd etc. - for MY board at
least - would not be much work. He said...naively!

Why not develop a nuttx based bootloader?
We have produced more than ten million devices, all run nuttx with
different configurations in the different phases(bootloader, ota, gui app),
cores(sensor hub, audio dsp), even security mode(tee).
The benefit of this approach include:
1. You just need write driver once and reuse in all possible scenario
2. Don't need learn and switch the development environment
When looking at Lup's work on porting NuttX to StarFive JH7110 SoC
(STAR64 and VisionFive2 boards) we were laughing that the whole NuttX
would be probably smaller than the UBoot itself :-)
Its a really nice idea but probably really lots of work :-)
