|
- phandlepart: which block storage device and partition the image loading from,
|
|
this property is required for mmc, usb and sata. This is unsigned
|
|
32-bit array. For example phandlepart=<&mmc_0 1>, meaning use
|

that MMC0 node pointer, partition 1.
|
|

Example of storage type and device partition search set for mmc, usb,
|
|
sata and ubi as shown in below:
|
|
Example for mmc:
|
|
fs_loader0: fs-loader@0 {
|
|
u-boot,dm-pre-reloc;
|
|
compatible = "u-boot,fs-loader";
|
|
phandlepart = <&mmc_0 1>;
|
|
};
|
|
|
|
Example for usb:
|
|
fs_loader1: fs-loader@1 {
|
|
u-boot,dm-pre-reloc;
|
|
compatible = "u-boot,fs-loader";
|
|
phandlepart = <&usb0 1>;
|
|
};

|
|
|
Example for sata:
|
|
fs_loader2: fs-loader@2 {
|
|
u-boot,dm-pre-reloc;
|
|
compatible = "u-boot,fs-loader";
|
|
phandlepart = <&sata0 1>;
|
|
};
|
|
|
|
Example for ubi:
|
|
fs_loader3: fs-loader@3 {
|
|
u-boot,dm-pre-reloc;
|
|
compatible = "u-boot,fs-loader";
|
|
mtdpart = "UBI",
