Upstreaming U-Boot is pretty much possible. Currently U-Boot status:

1. Functional screen output requires a patch in drivers/video/msxfb.c since the current U-Boot code doesn't not support 24/32b Serial RGB output mode.

2. No keypad driver: have to implement one for on-device console.

3. USB, I2C, PMIC, GPIO (LEDs) and NAND are functional.

Indeed, contacting upstream about those changes would be a good first step :)

Nice job, and good luck with upstreaming (as much as possible :))

As of today the UEFI is capable to bring up Windows 10 IoT into system shell. WinDbg is also available over UART connection.

Very good work :)
Minutes of boot time isn't exactly fun, but according to your tweet, the CPU isn't running at full clock speed, is it ? 396 MHz is just about the CPU frequency of the Prime G1 or the Nspire CX II series.

Yes 396MHz isn't the full speed, dynamic frequency scaling in system is not yet implemented.
