Greetings, 
i am using ELDK 2.6.26 distribution on MPC8349emds, 
arch = powerpc, cross_compile = ppc_6xx-

i've tried with uImage + FDT blob .dtb + uRamdisk
and i've added flash mapping in .dts as follow:

physmap-flash at 0xfc000000 {
		compatible = "amd,am29lv128ml", "cfi-flash";
		reg = <0xfc000000 0x04000000>;
		bank-width = <2>;
		device-width = <1>;
		#address-cells = <1>;
		#size-cells = <1>;
		uboot at 0 {
			label = "u-boot";
			reg = <0 0x000040000>;
		};
		uImage at 0x00080000 {
			label = "uImage";
			reg = <0x00080000 0x00100000>;
		};

		uRamdisk at 0x00180000 {
			label = "uRamdisk";
			reg = <0x00180000 0x00200000>;
		};
		mds at 0x00380000 {
			label = "MDS Device Tree";
			reg = <0x00380000 0x00800000>;
		};
		
	};

when i boot up the kernel on the board, i tried
# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 04000000 00020000 "physmap-flash.0"

and

# df
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/ram0                 5040      3756      1284  75% /

it does not shows flash device with df, and no partition under /proc/mtd,
can anybody help? 

in advance, thank you.
