Subject: [PATCH 03/10] MIPS: PCI: Byteswap not needed in little-endian mode
Date: Mon, 14 Jan 2013 21:41:55 +0530 [thread overview]
Message-ID: <1358179922-26663-4-git-send-email-jchandra@broadcom.com> (raw)
In-Reply-To: <1358179922-26663-1-git-send-email-jchandra@broadcom.com>
Wrap the xlp_enable_pci_bswap() function and its call with
'#ifdef __BIG_ENDIAN'. On Netlogic XLP, the PCIe initialization code
to setup to byteswap is needed only in big-endian mode.
