ow to define an uncached linker region

Can anyone tell me how to define a region in the linker to be uncached? An example - I have a block ram I am using for SGDMA descriptor tables that I need to define as uncached... Thanks - Chris

Mapping it to an address over 2^31 should do.

Note that the physical address (in SOPC etc) needs to have the top bit clear.
