No, that's not where it'll be; it'll relocate as high as it can.
I guess that's the confusing part. When I run with debug on I get the following log. Halfway down it reports "Now running in RAM - U-Boot at: eff89000", but there are still initcall's to lower memory after that. So I'm thinking lower memory is still used at that point. Am I wrong?
I did try a mem test starting at the lowest address and it worked, but I would like to understand why the initcall's to low-mem after relocation. The mem test essentially erases those addresses, so initcall's to those addresses are suspect at that point.

If you happen to have an SPL running from some RAM and not from DDR, then you could perform the full DDR test there. .
I think the mx53 has internal sram, which is why we were able to run fully from there before, since we had set CONFIG_SKIP_RELOCATE_UBOOT. I tried setting CONFIG_SKIP_LOWLEVEL_INIT, but nothing works with that set.
