IDMA on MPC8265

Hi,

I have an MPC8265 board with linux-2.4.20 as
OS and and a Gigabit Ethernet controller on
the PCI bus.

I have to implement a workaround, using one of
the IDMA channels, to avoid a deadlock caused
by PCI bus mastering of the GBE card.

Are there any mean pitfalls I should keep an
eye on, like using only certain regions of the
Dual Port RAM?

Thanks.
