AIUI, commit fffdf7290cee85232ee522e27c09c7f1178e6219 makes it work.  It
looks like it was included in 2020.07.  I was able to flash U-Boot onto
an ASUS C201 and now it boots nicely (and can be rolled back with a nice
little menu).  (I was gearing up to debug U-Boot myself, and am very
relieved someone beat me to it!)

I have the same problem with the kernel, and am using 5.4 currently.

I tried with Libreboot and with stock Depthcharge and had no luck.  I’m
pretty sure it’s a size issue, because every image I built bigger than
16M could not boot, but plenty of smaller ones could (if I made my own
initial RAM disk, say).  IIRC, upstream Depthcharge bumped the size
limit from 16M to 32M and that version should be included in Libreboot.
However, it didn’t work for me in practice.  Either way, I am much
happier using U-Boot.

That’s fair!  My glasses are a bit rosy right now because of my recent
success with U-Boot.
