    ACPICA: Add support for complex _PLD buffers. · be030a57
    Bob Moore 提交于
    _PLD (Physical Location of Device) returns a bit-packed buffer that
    is difficult to parse. This change adds a new interface,
    AcpiDecodePldBuffer that parses the buffer into a more usable
    local struct. Also adds macros to both get and set individual
    fields within the packed _PLD buffer. Adds a new include file,
    acbuffer.h - which will be expanded to add structs for other
    ACPI names that return buffers. ACPICA BZ 954.
    
    Emit (in comments) the decoded contents of a static _PLD buffer
    in order to improve comprehension of this bit-packed buffer.
    
    Add multi-endian support to the _PLD decode routine. Deploy the
    multi-endian macros to extract data from the _PLD buffer.
