Hi ,
I am using the OMAP2EVM board based on OMAP2430 and using Linux - 2.6.23
Is the DMA support available as part of the UART driver.
Thanks and Regards
Rajeev

Well there's an omap specific serial driver in works, which should
make it easy to add DMA support eventually. No idea on when it will be
available though, but some earlier patches are available at:
http://linux.omap.com/pipermail/linux-omap-open-source/2007-April/009537.html
AFAIK nobody is working on adding DMA to it yet, so that might be
worth doing.

The tar ball from the TI web site should have a working UART library
which is DMA enabled.
You likely can use that code with a little effort or can port the guts
into what Tony was pointing out.
