You want to map it into a free Data/Adressspace of  an  ARM  controllers
external memory?  No, not currently.  Only PCI/PCIe based ones.

I would go with a USB version of this controller,  OK, I  know  this  is
double work, but there are USB Host Controllers which can be maped  into
the memory space and then you can use any USB/SATA controllers you like.

I had several times the need for an ATAPI/ATA/SATA  controller  but  not
found one.

Generaly the ATAPI Protocoll is not very difficult and  can  implemented
in a 75MHz 8051 Flash controller with less then 32 kByte of Flash memory

The Maxim DS80C411 would work with it.

If someone is willing to implement the software, I could do the rest and
programming can be done In-House by the Chip-Manufacturer Maxim.

Oh, before I forget:  I have the source code for  8051  microcontrollers
(AN282) and USB mass-storage.  Since ist use a SiLabs C8051F340  with  a
SD, MMC and CF card, this code could be used for a ATA/ATAPI drive.

CF-Cards are ATAPI compatibel...

Maybethis woud work less expensive for us then looking for a dedicated
SATA/ATAPI controller which are mostly rather expensive mean 7+ US$.
