Hi everybody !
I am currently trying to add the support of partitions for the Flash chip on
my MPC8272ADS board (the chips are Sharp LH28F016SCT-L90).
I have added this part:
flash@0,0 {
compatible = "jedec-flash";
reg = <0x0 0x0 0x2000000>;
bank-width = <4>;
device-width = <1>;
partition@ff800000 {
label = "kernel";
reg = <0xff800000 0x00400000>;
read-only;
};
partition@ffc00000 {
label = "user";
reg = <0xffc00000 0x00300000>;
};
partition@fff00000 {
label = "u-boot";
reg = <0xfff00000 0x00100000>;
read-only;
};
};
But when I am compiling, I have these warnings:
Warning (reg_format): "reg" property in /localbus@f0010100/flash@0
,0/partition@ff800000 has invalid length (8 bytes) (#address-cells == 2,

Thanks in advance !

You are missing some definitions, The #address-cells and #size-cells = <1>;
tis is a snippet of teh dts i defined for my board.
flash@0,0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "cfi-flash";
reg = <0x0 0x0 0x08000000>;
bank-width = <4>;
device-width = <1>;
/* set flash partition to correspond tu mtd parts in
u-boot*/
/* 0xf8000000 */
partition@0x0 {
label = "factory-image";
reg = <0x00000000 0x01000000>;
};
/* 0xf9000000 */
partition@0x01000000 {
label = "app-image-1";
reg = <0x01000000 0x01000000>;
};

Hi do have these definitions, at a higher level:
localbus@f0010100 {
compatible = "fsl,mpc8272-localbus",
"fsl,pq2-localbus";
#address-cells = <2>;
#size-cells = <1>;
reg = <0xf0010100 0x40>;
ranges = <0x0 0x0 0xfe000000 0x2000000
0x1 0x0 0xf4500000 0x8000
0x3 0x0 0xf8200000 0x8000>;
flash@0,0 {
etc.

Hi do have these definitions, at a higher level:
The address-cells and size-cells definitions are not inherited. They
cover only the immediate children of the node where they appear.
Otherwise the default values apply (address-cells == 2, size-cells ==
1), which are not right for your case.

OK, so, after having tested, I can't see any changes when booting.
I do not have more mtd in /proc/mtd.

have you defined the following in your kernel config

I didn't have CONFIG_MTD_OF_PARTS=y.
Know, I have this output:

I think that the problem is in the reg part, but I can't understand why.
Isn't it the RAM mpping of my MTD that is the first address ?
Thanks agains,
