Alas I'm out of my depth on the topic regarding what to try next if
wanting to use the whole 1GB of RAM.
The workaround limiting RAM to 768MB works fine, and since no variant
seems to have over 1GB RAM, maybe it's acceptable tradeoff for most so
this hasn't seen more progress. The workaround in u-boot with the
adapter is described at
https://lists.debian.org/debian-arm/2018/06/msg00000.html , and after
setting that I've used my TS-221 for the past year. It can also be set
via fw_printenv and fw_setenv (not tested myself) as instructed at
fw_printenv gives me the following on the last line:
bootargs=console=ttyS0,115200 root=/dev/ram initrd=0xa00000,0x900000
