thoughts for next steps...

Jarielle,
Something to consider...
I think the next two big steps are:
- Init DRAM
- Boot standalone (using uSD instead of UART)
I believe your current plan was to work on DDR-init next; however it may be
better (your choice, just adding my 2cents) to consider booting from microSD
as the next task. Here's why I say that...
As you are playing with DDR-init you'll have to do a lot of restarting
the board.
Each time you do that, you'll have to reboot using Xmodem. This requires a
few manual steps: hold boot button while power cycling, then issue xmodem...
Alternatively, if you get the boot-from-uSD card stuff working, and then
erase
the eMMC (causing the cpu to automatically boot from uSD), you should be
able to just push the reset button to restart a locked up board.
It would just be easier (IMHO) if the board could reset with this basic
uMon image
(what you have running now) by default. Know what I mean? If yes, what
do you think?
