Subject: [PATCH 4/6] ARM: pci: make pcibios_assign_all_busses use pci_has_flag
Date: Wed, 29 Jun 2011 11:46:57 -0500 [thread overview]
Message-ID: <1309366019-24379-5-git-send-email-robherring2@gmail.com> (raw)
In-Reply-To: <1309366019-24379-1-git-send-email-robherring2@gmail.com>
From: Rob Herring <rob.herring@calxeda.com>
Convert pcibios_assign_all_busses from a define to inline so platforms can
control this setting.
Signed-off-by: Rob Herring <rob.herring@calxeda.com>
Acked-by: Nicolas Pitre <nicolas.pitre@linaro.org>
