    Subject[PATCH v3 4/5] ACPICA: Add new MADT GICC/GICR/ITS flags handling [code first]
    Date
    Add new flags and related fields to the MADT GICC/GICR/ITS
    structures according to the code first ECR:

    https://bugzilla.tianocore.org/show_bug.cgi?id=4557

    Temporary code waiting for ECR approval, for testing
    purpose only - eventually ACPICA changes will trickle
    into the kernel from the ACPICA project repos.
