+ARM Trusted Firmware - version 0.2
+* First source release.
+* Code for the PSCI suspend feature is supplied, although this is not enabled
+ by default since there are known issues (see below).
+Issues resolved since last release
+* The "psci" nodes in the FDTs provided in this release now fully comply
+ with the recommendations made in the PSCI specification.
+The following is a list of issues which are expected to be fixed in the future
+releases of the ARM Trusted Firmware.
+* The TrustZone Address Space Controller (TZC-400) is not being programmed
+ yet. Use of model parameter `-C bp.secure_memory=1` is not supported.
+* No support yet for secure world interrupt handling or for switching context
+ between secure and normal worlds in EL3.
+* GICv3 support is experimental. The Linux kernel patches to support this are
+ not widely available. There are known issues with GICv3 initialization in
+ the ARM Trusted Firmware.
+* Dynamic image loading is not available yet. The current image loader
+ implementation (used to load BL2 and all subsequent images) has some
+ limitations. Changing BL2 or BL3-1 load addresses in certain ways can lead
+ to loading errors, even if the images should theoretically fit in memory.
+* Although support for PSCI `CPU_SUSPEND` is present, it is not yet stable
+ and ready for use.
+* PSCI api calls `AFFINITY_INFO` & `PSCI_VERSION` are implemented but have not
+ been tested.
+* The ARM Trusted Firmware make files result in all build artifacts being
+ placed in the root of the project. These should be placed in appropriate
+* The compilation of ARM Trusted Firmware is not free from compilation
+ warnings. Some of these warnings have not been investigated yet so they
+ could mask real bugs.
+* The ARM Trusted Firmware currently uses toolchain/system include files like
+ stdio.h. It should provide versions of these within the project to maintain
+ compatibility between toolchains/systems.
+* The PSCI code takes some locks in an incorrect sequence. This may cause
+ problems with suspend and hotplug in certain conditions.
+* The Linux kernel used in this release is based on version 3.12-rc4. Using
+ this kernel with the ARM Trusted Firmware fails to start the file-system as
+ a RAM-disk. It fails to execute user-space `init` from the RAM-disk. As an
+ alternative, the VirtioBlock mechanism can be used to provide a file-system
+ to the kernel.
+Detailed changes since last release
+First source release – not applicable.
