Partly revert commit 726404a66c773 ("airoha: rework RAM size handling
to support multiple RAM size").
The general idea is good, but the call of
get_ram_size((void *)gd->ram_base, SZ_8G);
produces the following result on my an7581 board with only 1Gb of
memory:
"Synchronous Abort" handler, esr 0x96000004

Resetting CPU ...
So just not call get_ram_size() and use the value from dtb.
