Subject: [RFC PATCH V5 4/5] ARM64/PCI: Start using quirks handling for ACPI based PCI host controller
Date: Mon,  8 Aug 2016 15:05:40 +0200	[thread overview]
Message-ID: <1470661541-26270-5-git-send-email-tn@semihalf.com> (raw)
In-Reply-To: <1470661541-26270-1-git-send-email-tn@semihalf.com>

Since there are platforms which have non-compliant ECAM space we need to
override these accessors prior to PCI buses enumeration. In order to do
that we call pci_mcfg_match_quirks() to retrieve custom
pci_config_window structure. If no correlated quirk on list, use
fully ECAM compliant generic PCI config accessors.
