Subject: device tree question
Date: Tue, 18 Sep 2007 14:43:48 -0600 [thread overview]
Message-ID: <bfa0697f0709181343m1fc9f9b9u8acd429663d1adae@mail.gmail.com> (raw)
I want to make the mpc8272ads.dts tree work for my board.
I have an mpc8248
128MB Flash@ f800_0000 (Spansion S29GL512N)
128MB Flash@ D000_0000 (Spansion S29GL512N)
BCSR@e400_0000
2nd CSR@e410_0000
RAM@e420_0000
128MB SDRAM@[0x0..0800_0000]
Is it ok to have 0 in these:
cpus {
PowerPC,8272@0 {
. . .
timebase-frequency = <0>;
bus-frequency = <0>;
clock-frequency = <0>;
. . .
How do I modify the following lines to match my hardware?
localbus@f0010100 {
. . .
ranges = <0 0 fe000000 02000000
1 0 f4500000 00008000
3 0 f8200000 00008000>;
flash@0,0 {
compatible = "jedec-flash";
reg = <0 0 2000000>;
bank-width = <4>;
device-width = <1>;
};
board-control@1,0 {
reg = <1 0 20>;
compatible = "fsl,mpc8272ads-bcsr";
};
. . .
