| 3 | Required properties: |
| 4 | -------------------- |
| 5 | |
| 6 | - compatible: should contain "u-boot,fs-loader" |
| 7 | - phandlepart: which block storage device and partition the image loading from, |
| 8 | this property is required for mmc, usb and sata. This is unsigned |
| 9 | 32-bit array. For example phandlepart=<&mmc_0 1>, meaning use |
| 10 | that MMC0 node pointer, partition 1. |
| 11 | - mdtpart: which partition of ubi the image loading from, this property is |
| 12 | required for ubi and mounting. |
| 13 | - ubivol: which volume of ubi the image loading from, this property is required |
| 14 | for ubi and mounting. |

| 16 | Example of storage device and partition search set for mmc, usb, sata and |
| 17 | ubi in device tree source as shown in below: |
| 18 | |
| 19 | Example of storage type and device partition search set for mmc, usb, |
| 20 | sata and ubi as shown in below: |
| 21 | Example for mmc: |
| 22 | fs_loader0: fs-loader@0 { |
| 23 | u-boot,dm-pre-reloc; |
| 24 | compatible = "u-boot,fs-loader"; |
| 25 | phandlepart = <&mmc_0 1>; |
| 26 | }; |
| 27 | |
| 28 | Example for usb: |
| 29 | fs_loader1: fs-loader@1 { |
| 30 | u-boot,dm-pre-reloc; |
| 31 | compatible = "u-boot,fs-loader"; |
| 32 | phandlepart = <&usb0 1>; |
| 33 | }; |
| 34 | |
| 35 | Example for sata: |
| 36 | fs_loader2: fs-loader@2 { |
| 37 | u-boot,dm-pre-reloc; |
| 38 | compatible = "u-boot,fs-loader"; |
| 39 | phandlepart = <&sata0 1>; |
| 40 | }; |
| 41 | |
| 42 | Example for ubi: |
| 43 | fs_loader3: fs-loader@3 { |
| 44 | u-boot,dm-pre-reloc; |
| 45 | compatible = "u-boot,fs-loader"; |
| 46 | mtdpart = "UBI", |
| 47 | ubivol = "ubi0"; |
| 48 | }; |
