Hi all,
is there a standard way to define a ram chip (in my case a battery-buffered nv
ram, attached to the 5200's Local Bus) in the OF tree, and are there any
drivers (on 2.6.29.1) which pick up the chip/partition specification for mtd?
Does such a driver exist, or do I have to write one (probably based on
plat-ram.c?)? I think of something like
localbus {
[...]
ranges = < 0 0 0xfe000000 0x02000000
1 0 0xfc000000 0x00080000>;
fl...@0,0 {
[flash definition & partitions]
};
nv...@1,0 {
compatible = "mtd-ram";
reg = <1 0x0 0x00080000>;
bank-width = <2>;
device-width = <2>;
#size-cells = <1>;
#address-cells = <1>;
p...@0 {
label = "pdata";
reg = <0x00000000 0x00080000>;
};
};
};
Thanks,
Albrecht.
