+Changelog for qemu-linaro
+=========================
+
+Note that this changelog only covers ARM-related changes
+since the previous qemu-linaro release; since we track
+upstream fairly closely there will be various upstream
+changes which we incorporate but which are not listed
+here. For full change detail consult the git history:
+
+ http://git.linaro.org/gitweb?p=qemu/qemu-linaro.git;a=summary
+
+Bug numbers refer to Launchpad qemu-linaro bugs, eg:
+https://bugs.launchpad.net/qemu-linaro/+bug/703094
+
+version 2012.07:
+ - Fixes #1008338: QEMU built to use the 'Tiny Code
+ Interpreter' rather than JITting to native code now
+ works correctly (previously it would hang booting a
+ Linux guest).
+
+version 2012.06:
+ - No significant changes, rebased onto upstream v1.1.0.
+
+version 2012.05:
+ - Fixes #978694: Beagle bootrom emulation now correctly handles
+ FAT12/FAT16 images (thanks to Peter Chubb for the bug report
+ and patch).
+ - We now support running ARM BE8 userspace binaries (ie
+ byte-invariant big-endian data and little-endian code).
+
+version 2012.04:
+ - Fixes #928432: compiling spice support for i386 should
+ no longer give compile warnings/errors.
+ - Fixes #953544: 'SETEND' in Thumb mode should now UNDEF,
+ in line with the behaviour for the ARM encoding.
+ - Fixes #956799: add support for the ppoll syscall for
+ ARM linux-user emulation.
+ - Fixes #970252: add the OMAP36xx UART FIFO status registers
+ (thanks to Jan Vesely for the bug report and patch).
+
+version 2012.03:
+ - Fixes #932856: the OMAP3 boot rom emulation now tries
+ sector 256 in raw mode as well as sector 0.
+ - Fixes #931940: the PL031 RTC model now correctly raises
+ interrupts when the alarm timer expires.
+ - Fixes #928555: compiling on ARM systems with GLib 2.31
+ or better now works (we were previously failing due to
+ deprecation warnings on thread API functions).
+ - Fixes #885239: booting Linux on models using XScale CPUs
+ now works (a regression from upstream QEMU which has always
+ been present in qemu-linaro).
+ - Fixes #928432: compilation failures due to warnings in
+ Spice code on 32 bit hosts.
+ - Fixes #906922: we now default to enabling 'reserve memory
+ for guest' on 64 bit hosts in linux-user-mode. This
+ significantly reduces the chances of QEMU being unable to
+ satisfy a guest process mmap() request.
+ - Fixes #947888: the emulation of /proc/self/maps has been
+ improved. In particular the check for "%n in a format string
+ must be in a read-only area of memory" in the glibc in Ubuntu
+ Precise will now pass rather than always failing. (This was
+ causing some invocations of gpg to fail which in turn meant
+ using live-build to create Linaro images was failing.)
+ (Thanks to Alexander Graf of SuSE for these fixes.)
+ - QEMU's built-in boot loader now supports passing a device
+ tree blob to the kernel: if you boot with -kernel mykernel
+ (and optionally -initrd myinitrd) you can now also use the
+ new command line option -dtb my.dtb to pass a device tree.
+ - This version includes an initial implementation of a model
+ of the Samsung Exynos4210 SoC, used by board models 'nuri' and
+ 'smdkc210' (thanks to Evgeny Voevodin, Maksim Kozlov, Igor
+ Mitsyanko and Dmitry Solodkiy from Samsung, who submitted this
+ work to upstream QEMU).
+ - This version includes an initial implementation of a model
+ of the Calxeda Highbank SoC, used by board model 'highbank'
+ (thanks to Rob Herring and Mark Langsdorf of Calxeda, who
+ submitted this work to upstream QEMU).
+
+version 2012.02:
+ - Fixes #926102: prctl(PR_SET_NAME, ...) not supported. Fixes
+ usermode qemu running some perl scripts (as of perl 5.14).
+ - Fixes #913925: cpsie f instruction not reflected in FAULTMASK
+ (M profile)
+ - Simplified Cortex-A15 CPU definition, which can boot Linux.
+
+version 2012.01:
+ - Fixes #883133: we no longer assert on startup when running on
+ ARM systems with brk address space randomization enabled
+ - Fixes #870990: compiling on ARM systems for Thumb2 with
+ --enable-debug now works
+ - Fixes #903239: usermode emulation now includes support for
+ various previously missing *xattr syscalls
+ - Fixes #905697: trying to enable the prefetch engine in the
+ OMAP GPMC model might trigger an assertion failure
+ - We now have a (dummy) model of the L2x0/PL310 L2 cache
+ controller (thanks to Rob Herring and Mark Langsdorf)
+
+version 2011.12:
+ - There are no Linaro-specific changes of note in this release
+
+version 2011.11:
+ - The ARM vexpress-a9, versatilepb, versatileab and realview-*
+ boards now have audio support (thanks to Mathieu Sonet who
+ contributed a PL041 implementation upstream)
+ - Support for multiple instances of the "-sd" option on the
+ command line has been dropped; this was never present in
+ upstream QEMU and has been removed for consistency. Use
+ "-drive,if=sd,index=N,file=file.img" for N=0,1,2... instead
+ - Fixes #886980: 8 and 16 bit reads from the OMAP GPIO module
+ would crash due to an infinite recursion
+
+version 2011.10:
+ - Beagle models now support USB networking (run the model with
+ "-usb -device usb-net,netdev=mynet -netdev user,id=mynet")
+ - Instructions introduced with the Cortex-A15 (ARM mode
+ SDIV and UDIV, and the VFPv4 fused multiply-accumulate
+ instructions VFMA, VFMS, VFNMA, VFNMS) are now supported
+ in linux-user mode
+ - Fixes a bug which would cause returning of the wrong NaN values
+ in some cases (when more than one input is a NaN or when the
+ "default NaN" should be returned)
+
+version 2011.09:
+ - linux-user mode now supports the 64 bit cmpxchg kernel helpers
+ (only needed for applications compiled for ARMv6 or lower)
+ - correct a bug which would cause a crash trying to use USB
+ on the n800 and n810 models
+ - PL111 display controller now supported; this fixes a problem
+ where BGR was interpreted as RGB on recent versatilepb kernels
+ - Compilation failures on SPARC, ARM, ia64 fixed
+
+version 2011.08:
+ - Fixes #816791: ARMv6 cp15 barrier instructions now work
+ in linux-user mode as well as system mode
+ - Support for ARM1176JZF-S core has been added (thanks to
+ Jamie Iles <jamie@jamieiles.com>)

+ in 3.0) to suppress warnings about bad-width omap i2c accesses
+
+version 2011.07:
+ - Fixes a compile failure on ia64 hosts
+ - Fixes #728630: syscall 369 (prlimit64) implemented in
+ linux-user mode
+ - Fixes #802228: fix an ELF loader bug that caused problems
+ with binaries generated by the Google Go compiler
+
+version 2011.06:
+ - Introduces a model of the Gumstix Overo board ("overo")
+ - Fixes #708703: the OMAP3 OHCI USB controller is implemented
+ and works for USB keyboard and mouse
+ - Fixes #768650: suppresses a "Bad register 0x000000f8"
+ warning caused by the Linux kernel deliberately accessing
+ a non-existent OMAP3 interrupt controller register
+ - Models a DDC I2C slave to pass fake EDID monitor data,
+ to satisfy Linux kernels which insist on probing for a
+ monitor before turning on the display
+ - Fixes overflow when calculating result of signed VABAL
+ - Fixes handling of Neon UNDEF cases
+ - Fixes setting of floating point exception flags for
+ various Neon and VFP instructions
+ - Fixes corruption of base register for an abort midway

+ the set of registers to be loaded
+
+version 2011.04-1:
+ - Fixes a compilation failure with gcc 4.5
+
+version 2011.04-0:
+ - Fixes #731095: compiling for an ARM host in Thumb mode
+ now works (QEMU no longer segfaults on startup)
+ - Fixes #731279: compilation failures on SPARC Lucid fixed
+ - Some minor fixes to Neon corner cases (correctly handle
+ some UNDEF patterns, generate correct results for
+ VABAL, handle denormals and NaNs correctly in Neon floating
+ point arithmetic)
+
+version 2011.03-1:
+ - Fixes #731093: models with a PL181 (including vexpress-a9,
+ versatilepb and realview) would crash unless an SD card

+ 16550A compatibility; in particular Linux images using the
+ omap-hsuart driver can now boot to a shell prompt
+ - Fixes #714606: an SD card model bug was causing spurious
+ "not in Sending-Data state" messages on OMAP3
+ - Fixes #716336: should now compile on SPARC

+ to hang if it tries to enable a swapfile
+ - Has a number of minor ARM instruction correctness fixes
+ - Partial fix for #728630: linux-user mode now has a dummy
