Sheepish grin:  I did more checking, and the current mainline actually has
this set to 1 GB.

The .dts I'm using dates back to 2.6.25.  I had started modifying it for some
custom peripherals we have hacked onto a Sequoia, and I missed the changes
that were made between .25 and .28.

If you think 1 GB is a suitable default, then no further changes are needed.
If you think it should be bigger than 1 GB, then I could submit a patch.
