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

Using alt_remap_uncached() is supposed to make code more portable than changing bit 31 because it works with both MMU and non-MMU systems. I just say "supposed" because I never tested it myself
