+Subject: [PATCH] soc/fsl/qbman_portals: add APIs to retrieve the probing
+ status
+
+Add a couple of new APIs to check the probing status of the required
+cpu bound qman and bman portals:
+ 'int bman_portals_probed()' and 'int qman_portals_probed()'.
+They return the following values.
+ *  1 if qman/bman portals were all probed correctly
+ *  0 if qman/bman portals were not yet probed
+ * -1 if probing of qman/bman portals failed
+Portals are considered successful probed if no error occurred during
+the probing of any of the portals and if enough portals were probed
+to have one available for each cpu.
+The error handling paths were slightly rearranged in order to fit this
+new functionality without being too intrusive.
+Drivers that use qman/bman portal driver services are required to use
+these APIs before calling any functions exported by these drivers or
+otherwise they will crash the kernel.
+First user will be the dpaa1 ethernet driver, coming in a subsequent
+patch.
