U-Boot boot device (bootdev)
|
|
============================
|
|
|
|
A bootdev provides a way to obtain a bootflow file from a device. It is a
|
|
child of the media device (UCLASS_MMC, UCLASS_SPI_FLASH, etc.)
|
|
|
|
The bootdev driver is provided by the media devices. The bindings for each
|
|
are described in this file (to come).
|
|
|
|
Required properties:
|
|
|
|
compatible:
|
|
"u-boot,bootdev-eth" - Ethernet bootdev
|
|
"u-boot,bootdev-mmc" - MMC bootdev
|
|
"u-boot,bootdev-usb" - USB bootdev
|
|
|
|
|
|
Example:
|
|
|
|
mmc1 {
|
|
compatible = "sandbox,mmc";
|
|
|
|
mmc-bootdev {
|
|
compatible = "u-boot,bootdev-eth";
|
|
};
|
|
};
