I did but it must have gotten lost in the cosmos.

Well the price of the SOC has gained it some popularity, aswell as a 
couple forum posts.

It is very slow but its a good challenge.

I have tested this yes.

I'm Sending giulio.benetti@ some boards I made he will also test. I'm 
sure many other people will be willing to test aswell.

I can send you one of my many boards :)

It passes checkpatch on the latest.

NP!

I took https://github.com/Lichee-Pi/u-boot/tree/nano-v2018.01
re-based it against mainline and fixed formatting in a few files.
I also removed the spi-flash driver as it was causing issues and we can 
boot from sdcard for now. there are some things I did to make the old 
code compatible with new code but mostly preprocessor and configs.

For the dram driver I had to change a bit but none of the logic, i am 
worried that i may have to move it to /drivers.

Do you want a more comprehensive list of changes?
