+Similar to what we do for cpu type, the patch adds helper functions
+imx_set_soc_revision() and imx_get_soc_revision() to maintain
+imx_soc_revision in cpu.c.

+Date: Tue, 22 Oct 2013 21:51:26 -0700
+Subject: [PATCH] ARM: dts: add Gateworks Ventana support
+
+The Gateworks Ventana product family consists of several baseboard designs
+based on the Freescale i.MX6 family of processors. Each baseboard has a
+different set of possible features.

+Subject: [PATCH] imx: add PCI fixup for PEX860X on Gateworks board
+
+The PEX860X has GPIO's which are used for PCI Reset lines on the
+Gateworks Ventana boards. The GPIO's need to be set as output
+level high so as to allow the PCIe devices to come out of reset.

+Subject: [PATCH] PCI: imx6: remove outbound io/mem ATU region mapping
+
+The IMX6 iATU is used for address translation between the AXI bus
+address space and PCI address space. This is used for type0 and type1
+config cycles but is not necessary for outbound io/mem regions.
+
+This patch removes the calls that inappropriately re-configures the ATU
+viewport for outbound memory and IO after config cycles and removes them
+altogether as they are not necessary.
+
+This resolves issues with PCI devices behind switches and has been tested with
+a Gige device behind a PLX PEX860x switch.

+Subject: [PATCH] PCI: imx6: fix imprecise abort handler
+
+An imprecise abort is triggered when a port behind a switch is accessed
+and no device is present. At enumeration, imprecise aborts are not enabled
+thus this ends up getting deferred until the kernel has completed init. At
+that point we must not adjust PC - the handler must do nothing, but a handler
+must exist.
+
+This fixes random crashes that occur right after freeing init.
+This is against linux-pci/host-imx6.
