  To: u-boot

This patch adds support to iMX27ADS development board. This board has
128MB RAM, 32MB NOR Flash and 128MB NAND Flash. Currently only
booting from NOR is supported.

Dear Alan Carvalho de Assis,

You may (or may not  have  noticed)  that  we  have  reorganized  the
custodians  for  ARM  systems in the meantime. By now, Tom Rix is the
responsible custodian who is supposed to pick up this patch (assuming
there are no pending review comments for it).

AFAIK, Tom is on vacation this week, and I'm not sure if he has
network connectivity and/or time to work on this.

Best regards,

Wolfgang Denk

The list shall be kept sorted by maintainer name. So the mx27ads shall be moved.

The list is sorted alphabetically so move this down a bit.

I would insert a comma (,) after the first argument to the macro. Didn't know it worked without.
The same comment applies to the rest of this file. Don't know what the U-boot coding standard says about this though.
