+Subject: [PATCH] data/p10: Added backward support to pdbg compatible property
+
+The op-build ci will use released version of openbmc image and this image
+have pdbg library which is used p9 compatible property so, when using
+p10 targets compatible property value in generated device tree with that
+library, ipling is failing at 3.22 with following trace
+"No functional MC unit target found on master chip" at sbe side.
+So, added p9 targets compatible property value to support previous released
+version of bmc image.
+
+To use updated pdbg version in bmc, bmc will expect respective device tree
+and the device tree is one of partition in pnor image and this image will
+build in op-build so, there is cyclic dependency between bmc and pnor image
+to release. To avoid cyclic dependency in image added backward support.
+
+Once bmc image released with updated pdbg version to support
+p10 targets compatible property value then this patch should reverted.
+
