Hi,

working solutions beat ideal solutions.

If y'all have a patched chain-loading u-boot that can then itself chainload
our loader and have that chainload freebsd, then please:

* create a git tree somewhere;
* get an upstream copy of u-boot 2025.04 into it;
* add whatever diffs you need to get freebsd's loader chainloading from it;
* add documentation on how it works;
* let's get it working.

The RP1 silicon looks cool; I wish I had time to go write stuff for that
but my plate is full.

Don't worry about the "correct freebsd way", we already have a bazillion
u-boot 2025.04 forked ports ("pkg search u-boot" on your local freebsd).
I know people prefer a UEFI interface, and if someone has a maintained one,
great! create a port and ship it!
But otherwise, I really just recommend the "smash the keyboard to
demonstrate it working, and let's get it into a bootloader port" path.

I'd hate to see work go to waste. Let's get it into a github repo forked
off of 2025.04 to match the rest of our current bootloader ports
and churn on whatever's needed to get it done and shipping.
