Subject: [PATCH] sparc/PCI: Add IORESOURCE_MEM_64 for 64-bit resource in of parsing
Date: Wed, 08 Apr 2015 00:24:18 +0000 [thread overview]
Message-ID: <1428452658-24787-1-git-send-email-yinghai@kernel.org> (raw)
For device resource PREF bit setting under bridge 64-bit pref resource,
we need to make sure only set PREF for 64bit resource, so set IORESOUCE_MEM_64
for 64bit resource during of device resource flags parsing.
