+ Library of userspace helpers specific for the Freescale i.MX
+ platform. It wraps the kernel interfaces for the i.MX platform
+ Video Processing Unit (VPU) driver. It requires a kernel that
+ includes the i.MX specific headers to be built.
+
+ This library is provided by Freescale as-is and doesn't have
+ an upstream.

+[PATCH] vpu-io: fix IOSystemInit failure
+
+When using a kernel where user/kernel split is 3G/1G, the address
+returned by IOGetVirtMem() can appear to be a negative int.
+
+IOSystemInit() incorrectly checks the return value of IOGetVirtMem().
+IOGetVirtMem() returns -1 on error (and not MAP_FAILED, nor any other
+negative value.)
+
+Fix that by correctly checking against -1 (and not MAP_FAILED!)
