This disptacher populates the following structures:
|
|
- CM_ARM_GICC_INFO
|
|
- CM_ARM_GICD_INFO
|
|
- CM_ARM_GIC_MSI_FRAME_INFO
|
|
|
|
A parser parses a Device Tree to populate a specific CmObj type. None,
|
|
one or many CmObj can be created by the parser.
|
|
The created CmObj are then handed to the parser's caller through the
|
|
HW_INFO_ADD_OBJECT interface.
|
|
This can also be a dispatcher. I.e. a function that not parsing a
|
|
Device Tree but calling other parsers.
|
|
|
|
@param [in] FdtParserHandle A handle to the parser instance.
|
|
@param [in] FdtBranch When searching for DT node name, restrict
|
|
the search to this Device Tree branch.
|
|
|
|
@retval EFI_SUCCESS The function completed successfully.
|
|
@retval EFI_ABORTED An error occurred.
|
|
@retval EFI_INVALID_PARAMETER Invalid parameter.

@retval EFI_NOT_FOUND Not found.
