First run of removing code specific to CSB740/OMAP3530 and replacing it with that of BBB/AM335xin BBB port

[Ed Sutter]

Jarielle,
Ok, I think I'm where you are now.  Good job with the patches!
Note, I'm *still* not using the RTEMS compiler (which I need to do).  I
just wanted to walk through some of the patches to see if I could get
to your state.  Building it this way, it appears that I have the same problem
you've been talking about.  On the other hand, if I build off of umon1.19
there is no problem (which, again, I think is the same thing you reported).

I had to make two changes after applying all the patches you submitted, but
you must have them already.  Let me know if you disagree...

They are regarding the BOOTROMBASE/BOOTRAMBASE variables in the Makefile
and the UART base address in config.h.

The intelligent thing at this point would be to back off and install the RTEMS
compiler; however, its too late to start that now so I'm just gonna play around
with this for an hour or so...
Ed
