Ah, then it must be connected via MPC8347's localbus. 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: local...@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 sd...@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... -- Anton Vorontsov email: cbouatmai...@gmail.com irc://irc.freenode.net/bd2 _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
