How did you come to this conclusion? From the node above it's IMHO pretty clear that IDE (PATA) is on the localbus. The driver is drivers/ata/pata_of_platform.c. > controls PCI-based IDE-controller where we can plug in our CF card...Am I > right??? Nope, no PCI involved.

Yes, that's exactly how CF is done on MPC8349EmITX boards. > Can you please explain how the interface is implemented in MPC8349.. Via localbus + UPM. * 'almost' is because there are some buffers and inverters, see schematics: http://www.freescale.com/files/32bit/hardware_tools/schematics/MPC8349EMITXESCH.pdf -- Anton Vorontsov email: cbouatmai...@gmail.com irc://irc.freenode.net/bd2 _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
