Grant, your SPI driver works with MMC cards. I needed to add the patch
noted above.

What's the status of merging Anton's patch?

And then tweak names until everything matches.

		spi@f00 {
			#address-cells = <1>;
			#size-cells = <0>;
			compatible = "fsl,mpc5200b-spi","fsl,mpc5200-spi";
			reg = <0xf00 0x20>;
			interrupts = <0x2 0xd 0x0 0x2 0xe 0x0>;
			interrupt-parent = <&mpc5200_pic>;

			mmc-slot@0 {
				compatible = "linux,mmc-spi";
				reg = <0>;
				spi-max-frequency = <20000000>;
				/* Unregulated slot. */
				voltage-range = <3300 3300>;
				/*gpios = <&sdcsr_pio 1 0   /*  WP */
				/*		 &sdcsr_pio 0 1>; /* nCD */
			};
		};
