[microblaze-uclinux] Avnet CMM/Microblaze

Has anybody gotten the SDRAM on an Avnet Communications Memory Module
to work with a Spartan 3-based Microblaze and uClinux?  It has a
beautiful 64MB of SDRAM that will allow me to move beyond my current
1MB system.  But I'm having trouble just reading/writing to memory via
XMD.

Values that I write out to any 1 32-bit word are getting read back from
_every_ memory word read location.  And then 16-bit writes only write
out the lower 8 bits.  And I read back the same value from 16-bit read
even though I only did 1 write.

Thanks for any suggestions on things to look at....  I've done a
compare of the opb_sdram and Micron datasheets and am pretty sure I
have the various opb_sdram parameters set up correctly.

Steve
