From: Pierre Gondois <pierre.gond...@arm.com> The ACPI specification, version 6.3, January 2019, defines the Named Objects Encoding for FieldElements in section '20.2.5.2 Named Objects Encoding'. FieldElements can be one of the following: NamedField | ReservedField | AccessField | ExtendedAccessField | ConnectField
Some of these keywords are starting with an opcode, allowing to identify their type. E.g.: ReservedField := 0x00 PkgLength This patch adds these FieldElement opcodes definitions to the list of AML Opcode definitions.
