In case it helps, the thead fork of u-boot contains an important file
include/configs/light-c910.h that defines the boot scripts for each
board. Here is the BeagleV Ahead:
https://git.beagleboard.org/beaglev-ahead/beaglev-ahead-u-boot/-/blob/beaglev-v2020.01-1.1.2/include/configs/light-c910.h#L361
It might give some clues as to want commands to try.
From the lpi4a config:
https://github.com/revyos/thead-u-boot/blob/09e2c3f93f1a64c10ca51d9b9c0c22fbc0947c43/configs/light_lpi4a_defconfig
It looks like it sets:
CONFIG_TARGET_LIGHT_FM_C910_LPI4A=y
And that corresponds to:
https://github.com/revyos/thead-u-boot/blob/09e2c3f93f1a64c10ca51d9b9c0c22fbc0947c43/include/configs/light-c910.h#L425
Anyways, I finally got my Lichee Pi 4a out of the box, and I am going
to try it out too.
