+ u-boot,dm-pre-reloc;
+ compatible = "fs_loader";
+ storage_device = "mmc";
+ devpart = "0:1";
+ };
+
+Example for usb:
+ fs_loader {
+ u-boot,dm-pre-reloc;
+ compatible = "fs_loader";
+ storage_device = "usb";
+ devpart = "0:1";
+ };
+
+Example for sata:
+ fs_loader {
+ u-boot,dm-pre-reloc;
+ compatible = "fs_loader";
+ storage_device = "sata";
+ devpart = "0:1";
+ };
+
+Example for ubi:
+ fs_loader {
+ u-boot,dm-pre-reloc;
+ compatible = "fs_loader";
+ storage_device = "ubi";
