To be honest, I didn't tell you that there are still issues with my
mpc85xx_map_irq() and friends(). I didn't fix the table for my board
yet as the official CR854 demo board has only on PCI slot and I just
didn't care about proper IDSEL->IRQ mapping.
The hardware add-on we design should be compatible to the ADS board (or to
be precise to the default mpc8540_ads behaviour in the kernel) as much
as possible, so there should be no need for a separate platform port.

Yes, but AFAIK it's only 32bit/33MHz PCI and therefore not speedy enough for
the things we want to achieve (100..200Mbyte+/sec).
So, this problem with the PDC has to be fixed... but it will take some time.
Best greets,
Clemens Koller
