+skiboot-5.2.3
+-------------
+
+skiboot-5.2.3 was released on Thursday June 30th, 2016.
+
+skiboot-5.2.3 is the 4th stable release of skiboot 5.2, the new stable
+release of skiboot, which takes over from the 5.1.x series which was
+first released August 17th, 2015.
+
+Skiboot 5.2.3 replaces skiboot-5.2.2 as the current stable version, which was
+released on May 5th, 2016. Over skiboot-5.2.2, skiboot 5.2.3 contains
+one important bug fix regarding parsing data from the OCC regarding CPU
+frequency tables, which could lead to no CPU frequency scaling.
+
+skiboot-5.2.3 contains all bug fixes as of skiboot-5.1.16.
+
+This is the second release that will follow the (now documented) Skiboot
+stable rules - see doc/stable-skiboot-rules.txt.
+
+Over skiboot-5.2.2, the following fixes are included:
+
+OpenPOWER platforms:
+- occ: Filter out entries from Pmin to Pmax in pstate table
+  (cherry picked from commit eca02ee2e62cee115d921a01cea061782ce47cc7)
+  Without this fix, with newer OCC firmware on some OpenPOWER machines,
+  we would fail to parse the table from the OCC, which meant the host OS
+  would not get a table of supported CPU frequencies.
+
+General:
+- pci: Do a dummy config write to devices to establish bus number
+  (cherry picked from commit f46c1e506d199332b0f9741278c8ec35b3e39135)
+
+    On PCI Express, devices need to know their own bus number in order
+    to provide the correct source identification (aka RID) in upstream
+    packets they might send, such as error messages or DMAs.
+
+    However while devices know (and hard wire) their own device and
+    function number, they know nothing about bus numbers by default, those
+    are decoded by bridges for routing. All they know is that if their
+    parent bridge sends a "type 0" configuration access, they should decode
+    it provided the device and function numbers match.
+
+    The PCIe spec thus defines that when a device receive such a configuration
+    access and it's a write, it should "capture" the bus number in the source
+    field of the packet, and re-use as the originator bus number of all
+    subsequent outgoing requests.
+
+    In order to ensure that a device has this bus number firmly established
+    before it's likely to send error packets upstream, we should thus do a
+    dummy configuration write to it as soon as possible after probing.
+- Fix GCC 6 warning in backtrace code
+  (cherry picked from commit 793f6f5b32c96f2774bd955b6062c74a672317ca)
+- Backport of user visible typo fixes
+  partial cherry picked from 4c95b5e04e3c4f72e4005574f67cd6e365d3276f
+
+Utilities:
+- Fix ARM build failure with parallel make
