From 3f6ea84a3035cc0ef7488f8e93bc76766799e082 Mon Sep 17 00:00:00 2001 From: "Ira W. Snyder" Date: Thu, 1 Apr 2010 11:43:30 -0700 Subject: PCI: read memory ranges out of Broadcom CNB20LE host bridge Read the memory ranges behind the Broadcom CNB20LE host bridge out of the hardware. This allows PCI hotplugging to work, since we know which memory range to allocate PCI BAR's from. The x86 PCI code automatically prefers the ACPI _CRS information when it is available. In that case, this information is not used. Signed-off-by: Ira W.
