Well, it's just what is says. Your U-Boot doesn't fit in ram.

Try increasing CONFIG_SPL_MAX_SIZE and then use linux/scripts/bloat-o-meter
to see where the growth is.

But the main thing is that U-Boot is tested with the latest GCC, and older
versions tend to have worse optimization.

The easiest way to get a newer GCC is to download one from [1]. Since you
are on focal, you could also try [2] (but that only provides GCC 11).
