Hi 

Thank you for your reply again.
Ah, then it must be connected via MPC8347's localbus.
That's right.

I will try it,and I inform them of the result.

Hi 

Thank you for your reply.
I know RICOH has PCI SD/MMC controller. But R5C807 RICOH is not the PCI device
which is probably new product.

Well, then you need 2.6.29-rcX kernels, for example
http://www.kernel.org/pub/linux/kernel/v2.6/testing/linux-2.6.29-rc8.tar.bz2
is suitable.

Untar it and apply the patches (they'll apply fine on that
kernel). Then you'll need some device tree additions for
your MPC8347 board, something like this:

       localbus@e0005000 {
               #address-cells = <2>;
               #size-cells = <1>;
               compatible = "fsl,mpc8347-localbus",
                            "fsl,pq2pro-localbus";
               reg = <0xe0005000 0xd8>;
               ranges = <0x1 0x0 0xf0000000 0x1000>;
	// ^^ change the 0xf0000000 to the actual address
               sdhci@1,0 {
                       compatible = "ricoh,r5c807", "generic-sdhci";
                       reg = <0x1 0x0 0x1000>;
                       interrupts = <ricoh-interrupt-here 0x8>;
                       interrupt-parent = <&ipic>;
                       // if needed, clock-frequency = <freq-in-HZ-here>;
               };
       };

Note that I'm not sure what endiannes you'll get when connecting
the ricoh chip to the big-endinan host...
