[microblaze-uclinux] DCM wrapper

[John Williams <jwilliams@itee.uq.edu.au>]

Hi folks,

Is anybody interested in the wrapper I have put around the DCM 
primitive?  It's not rocket science, just allows easy use of the DCM 
clock synthesis capabilities within an XPS/EDK project.  Currently the 
clock divisor and multiplier factors, and the input clock period are 
parameterisable via the MPD mechanism, but there's no reason it couldn't 
be made more generic.

I like to work with the XST flow, without having to switch over to 
Project Navigator, which is what prompted this little experiment in 
wrapping primitives into the EDK flavour.  It is now possible to 
generate arbitrary system clock frequencies for microblaze targets all 
from within the XPS environment (or equivalently by editing the MHS file).

This wrapper will probably become "standard" in the mbvanilla target 
once I get it integrated.

Cheers,

John
