The message "DRAM: 2 GiB (effective 32 GiB)" can be a little confusing, modify the message to show exactly what is meant:

I've forgotten why the first number can be so much lower than the second. What is causing that?
This is quite a long string...could we say "(total 32 GiB)" ? Then perhaps add something to doc/ to talk about the banner that U-Boot prints?
Why not just only print the total number? The amount available to U-Boot seems like an internal detail, I'd guess most folks just what to see at a glance how much DDR was detected on their system.
Knowing how much u-boot is using might help someone who is working on some memory map related stuff or if they want to stop at u-boot prompt and tweak environment variables related to memory map (e.g. load address for kernel, dtb, load bitmap to DDR etc). Overall I personally don't see much harm on keeping both the information (DDR available to u-boot and total available DDR). If the word effective is confusing than the print can be made more verbose as being intended in this patch-set or by following the suggestions given by Simon and Udit.
U-Boot isn't "using" 2GiB however. And in fact the command Simon is working on to dump the memory table and what's where, as far as U-Boot knows, would be helpful in that case.
