* QE Firmware Node
|
||||
|
||||
This node defines a firmware binary that is embedded in the device tree, for
|
||||
the purpose of passing the firmware from bootloader to the kernel, or from
|
||||
the hypervisor to the guest.
|
||||
|
||||
The firmware node itself contains the firmware binary contents, a compatible
|
||||
property, and any firmware-specific properties. The node should be placed
|
||||
inside a QE node that needs it. Doing so eliminates the need for a
|
||||
fsl,firmware-phandle property. Other QE nodes that need the same firmware
|
||||
should define an fsl,firmware-phandle property that points to the firmware node
|
||||
in the first QE node.
|
||||
|
||||
The fsl,firmware property can be specified in the DTS (possibly using incbin)
|
||||
or can be inserted by the boot loader at boot time.
|
||||
|
||||
Required properties:
|
||||
- compatible
|
||||
Usage: required
|
||||
Value type: <string>
|
||||
Definition: A standard property. Specify a string that indicates what
|
||||
kind of firmware it is. For QE, this should be "fsl,qe-firmware".
|
||||
|
||||
- fsl,firmware
|
||||
Usage: required
|
||||
Value type: <prop-encoded-array>, encoded as an array of bytes
|
||||
Definition: A standard property. This property contains the firmware
|
||||
binary "blob".
|
||||
|
||||

|
||||
qe1@e0080000 {
