Subject: [PATCH 14/15] [POWERPC] Let subordinate transparent bridges be transparent.
Date: Tue, 26 Jun 2007 20:16:44 -0500 [thread overview]
Message-ID: <1182907026390-git-send-email-galak@kernel.crashing.org> (raw)
In-Reply-To: <11829070241688-git-send-email-galak@kernel.crashing.org>
From: York Sun <yorksun@freescale.com>
In pcibios_fixup_bus(), bridges that are subordinate
to transparent bridges were still relocating their
IORESOURCE_IO and IO_RESOURCE_MEM start and end values.
Fix this by preventing the transparent bridge from
relocating the start and end values, thus allowing the
subordinate non-transparent bridge full molestation rights.
