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

CM_ARM_BOOT_ARCH_INFO parser function.

The following structure is populated: typedef struct CmArmBootArchInfo { UINT16 BootArchFlags; // {Populated} } CM_ARM_BOOT_ARCH_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.

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.
