Subject: [PATCH 04/50] ACPICA: Fix to allow region arguments to reference other scopes
Date: Tue, 17 Jan 2012 07:20:56 -0500	[thread overview]
Message-ID: <8931d9ea78848b073bf299594f148b83abde4a5e.1326802229.git.len.brown@intel.com> (raw)
In-Reply-To: <1326802902-21583-1-git-send-email-lenb@kernel.org>
In-Reply-To: <553575f1ae048aa44682b46b3c51929a0b3ad337.1326802228.git.len.brown@intel.com>

From: Lin Ming <ming.m.lin@intel.com>

Allow referenced objects to be in a different scope.

ACPI Error: [RAMB] Namespace lookup failure, AE_NOT_FOUND (20110112/psargs-359)
ACPI Exception: AE_NOT_FOUND, Could not execute arguments for [RAMW] (Region) (20110112/nsinit-349)

    Scope (_SB)
    {
        Name (RAMB, 0xDF5A1018)
        OperationRegion (\RAMW, SystemMemory, RAMB, 0x00010000)
    }

For above ASL code, we need to save scope node(\_SB) to lookup
the argument node(\_SB.RAMB).
