[U-Boot] [PATCH 1/3] Revert "i.MX28: Enable additional DRAM address bits"

[Detlev Zundel <dzu@denx.de>]

Hi Marek,

To be honest, I don't understand what this patch or what the original
patch did, nor through what OOT port this hit mainline and what breakage
it causes on other boards.

So also I can read the sentence, I cannot make heads and tails of it.
Can you please write commit messages that people like me can make some
sense from?  I.e. answering the following questions would help me

- What does the original commit do? (its too late to change the original
  commit) 
- Why was the change made in the first place and for what OOT port?
- What breakage is caused on what boards?
- Why can we revert the change without any problems?

Thanks
  Detlev
