+Subject: [PATCH] arm64: dts: Update cache properties for Arm Ltd platforms
+
+The DeviceTree Specification v0.3 specifies that the cache node
+"compatible" and "cache-level" properties are required.
+
+Cf. s3.8 Multi-level and Shared Cache Nodes
+The 'cache-unified' property should be present if one of the properties
+for unified cache is present ('cache-size', ...).
+
+Update the relevant device trees nodes accordingly.

+Subject: [PATCH] arm64: dts: fvp: Add SPE to Foundation FVP
+
+Add SPE DT node to FVP model. If the model doesn't support SPE (e.g.,
+turned off via parameter), the driver will skip the initialisation
+accordingly and thus is safe.

+
+Add the information about L1 and L2 caches on FVP RevC platform.
+Though the cache size is configurable through the model parameters,
+having default values in the device tree helps to exercise and debug
+any code utilising the cache information without the need of real
+hardware.
