ArchFdtHwInfoMainDispatcher()

EFI_STATUS EFIAPI ArchFdtHwInfoMainDispatcher	(	IN CONST FDT_HW_INFO_PARSER_HANDLE	FdtParserHandle,
		IN INT32	FdtBranch
	)

Main dispatcher: sequentially call the parsers/dispatchers of the HwInfoParserTable.

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.

Parameters

[in]	FdtParserHandle	A handle to the parser instance.
[in]	FdtBranch	When searching for DT node name, restrict the search to this Device Tree branch.

Return values

EFI_SUCCESS	The function completed successfully.
EFI_ABORTED	An error occurred.
EFI_INVALID_PARAMETER	Invalid parameter.
EFI_NOT_FOUND	Not found.
EFI_UNSUPPORTED	Unsupported.
