[ELDK] TQM5200: IDE not in UDMA mode, hdparm not working

[Marc Scherer]

Is it possible to use the IDE-Interface in UDMA2 mode with the TQM5200?

We have a Debian Lenny running on a TQM5200 on a STK52xx with a
Denx-Linux-Kernel 2.6.33 in the Denx default configuration (make
52xx/tqm5200_defconfig). We can do hdparm -I or hdparm -i (output see below)

However, all hdparm commands like

hdparm -d /dev/sda

fail with

/dev/sda:
 HDIO_GET_DMA failed: Inappropriate ioctl for device

In general, it is impossible to set anything, there is always the error
"Inappropriate ioctl for device".

Is this a kernel config issue, or a mismatch Denx-Kernel /
Debian-hdparm, or is it just not possible with the TQM5200?

Thank you for any comments,
Marc Scherer

Here is the output of the info commands:
