Thank's a lot. Should have looked into it, that was really a simple

I'm sorry, but if I would know about the details, and would know more
about ATA I would have tried to patch pata_mpc52xx.c by myself.
Even better, just send the driver upstream.
It has been there for a long while. You even patched it last summer.

Subject: [PATCH] mpc52xx_gpio: support MPC52xx simple interrupt GPIO
Add two OF GPIO chips when probing fsl,mpc5200-gpio, one for the 32

And which one is good or better for CAN+MPC52xx if that's

Hello,
This patch avoids unbalanced enable/disable messages for the DMA
interrupts when running the 5200 platform SCLPC/BestComm driver in DMA

(HW guys), esp. when reading Freescale's
advice with the XLB config.
It might happen that we switch to 2.6 on our older products, hoping
that at least the LPC/IDE problem disappears by using MWDMA2 instead
of UDMA2.

. Looking at it a second time you and Wolfgang are definitively
right. And I prefer the (1n) style a lot more than the 0x0080 style.
Why is the list head being removed?
Not used at all, except in initialization?
Of course a seperate patch would have been needed.

The order of the raised interrupts of SCLPC and BCOM cannot be
predicted, because it depends on the individual BCOM and CPU loads. So
in DMA mode we just wait for both until we finish the transaction.

might be increasing the number of BDs again, because the
BestComm seems to take some time until it gives them back to the
world, and then sometimes in batches. I had a similar problem on a
high speed SPI link using the BestComm.

concurrent traffic to or from the LPC (chips selects of peripherals
while a DMA transfer is active).
The same disks work without problems using UDMA2 on the old 2.4.25 on
exctly the same HW. Why? I don't know yet.

on
e.g. FEC or ATA can delay the bcom gen bd interrupt until it's task
gets scheduled again, which can take some time due its low BestComm
prio of 2. The second problem was, that the original driver does not
use the flush bit to avoid stale RX data.

did not manually flush or invalidate the cache prior to the DMA

not find that file, neither in the current master, nor in older tags

If you are using older kernel you may want to copy it.
