Subject: [U-Boot] [PATCH] armv8/fsl-layerscape: add IFC fixup for LS1043A with QSPI enabled
Date: Mon, 22 Feb 2016 18:05:20 +0800 [thread overview]
Message-ID: <1456135520-48373-1-git-send-email-Qianyu.Gong@nxp.com> (raw)
QSPI and IFC are pin-multiplexed on LS1043A. So if QSPI is enabled,
IFC should be disabled.
But just disable IFC driver in LS1043A Linux is not enough because
mdio-mux will access IFC address space -- actually it accesses FPGA
which is connected to IFC CS3. So disable the whole IFC node in
Linux device tree.
