So is there a fix to be had by maybe shifting both CONFIG_SPL_TEXT_BASE and CONFIG_SYS_TEXT_BASE a little bit?

It looks like there's some issue if the total flash image size is
over 512KiB. (The physical flash chip is 1MiB). I'm investigating
whether this is expected and what to do about it. The change to
CONFIG_SYS_TEXT_BASE accidentally solves this, since it currently
happens to shrink the image size enough not to hit this apparent limit.

Changing CONFIG_SPL_TEXT_BASE won't have any effect on this; size matters not location.

As I mentioned, changing CONFIG_SYS_TEXT_BASE currently avoids the issue, but hopefully we can find something better.
