Just an update, I've had the kernel up and running a continuos "find" 
command for the last 11 hours using the hardcoded DDR memory controller 
values, so there's definitely something wrong with using SPD and the 
memory that's installed on my 8349itx board.  Still working on figuring 
out spd_sdram().

I'll just float this out there in case anyone has a suggestion. 
spd_sdram() runs (obviously) before the RAM is available.  So all my 
variables are in the cache (which by the way is a really slick idea), but 
I can seem to access those variables with the BDI or GDB.  I get a "Cannot 
access memory at address 0xfd000ee8" message.  This message is a bit odd 
to me since I'm "accessing" that memory location through the processor 
itself, and I know the processor can access that memory, because it's 
stack is also in the cache and it successfully boots therefore it can 
access the memory.  So why can't I?  I'm sure it's some thing subtle that 
I haven't yet learned about the 8349, but if any one could slap me up side 
the head and point out the obvious that I'm missing I would appreciate it.

Thanks.
