Deal with devices that just exist in memory space.
|
||
|
|
|
||
|
|
To follow the EFI driver model you need a root handle to start with. An
|
||
|
|
EFI driver will have a driver binding protocol (Supported, Start, Stop)
|
||
|
|
that is used to layer on top of a handle via a gBS->ConnectController.
|
||
|
|
The first handle has to just be in the system to make that work. For
|
||
|
|
PCI it is a PCI Root Bridge IO protocol that provides the root.
|
||
|
|
|
||
|
|
On an embedded system with MMIO device we need a handle to just
|
||
|
|
show up. That handle will have this protocol and a device path
|
||
|
|
protocol on it.
|
||
|
|
|
||
|
|
For an ethernet device the device path must contain a MAC address device path
|
||
|
|
node.
