Check the p2020rdb-pc.dtsi file.
Find the following:
reg = <0x0 0x0 0x8000000>;
/* reg = <0x0 0x0 0x10000000>; */
This file shows that NOR 128MBytes is used and virtual addresses are from 0 to 0x8000000.
Check the following in this file:
partition@ff00000 {
/* This location must not be altered */
/* 512KB for u-boot Bootloader Image */
/* 512KB for u-boot Environment Variables */
reg = <0x0ff00000 0x00100000>;
This partition requires virtual address 0x0x0ff00000.
It looks like the following configuration should be used:
&lbc {
nor@0,0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "cfi-flash";
reg = <0x0 0x0 0x8000000>;
/* reg = <0x0 0x0 0x10000000>; */
bank-width = <2>;
device-width = <1>;
partition@0 {
/* This location must not be altered */
/* 256KB for Vitesse 7385 Switch firmware */
reg = <0x0 0x00040000>;
label = "NOR Vitesse-7385 Firmware";
read-only;
};
partition@40000 {
/* 256KB for DTB Image */
reg = <0x00040000 0x00040000>;
label = "NOR DTB Image";
};
partition@80000 {
/* 3.5 MB for Linux Kernel Image */
reg = <0x00080000 0x00780000>;
label = "NOR Linux Kernel Image";
};
partition@800000 {
/* 11MB for JFFS2 based Root file System */
/*reg = <0x00400000 0x00b00000>;*/
reg = <0x00800000 0x00B00000>;
/* reg = <0x00800000 0x10000000>; */
label = "NOR JFFS2 Root File System";
};
partition@ff00000 {
/* This location must not be altered */
/* 512KB for u-boot Bootloader Image */
/* 512KB for u-boot Environment Variables */
/* 1MB */
reg = <0x01300000 0x00100000>;
label = "NOR U-Boot Image";
read-only;
};
};
Have a great day,
