target/i386: Add Intel HAX files
That's a forward port of the core HAX interface code from the emu-2.2-release branch in the external/qemu-android repository as used by the Android emulator. The original commit was "target/i386: Add Intel HAX to android emulator" saying: """ Backport of 2b3098ff27bab079caab9b46b58546b5036f5c0c from studio-1.4-dev into emu-master-dev Intel HAX (harware acceleration) will enhance android emulator performance in Windows and Mac OS X in the systems powered by Intel processors with "Intel Hardware Accelerated Execution Manager" package installed when user runs android emulator with Intel target. Signed-off-by: David Chou <david.j.chou@intel.com> """ It has been modified to build and run along with the current code base. The formatting has been fixed to go through scripts/checkpatch.pl, and the DPRINTF macros have been updated to get the instanciations checked by the compiler. The FPU registers saving/restoring has been updated to match the current QEMU registers layout. The implementation has been simplified by doing the following modifications: - removing the code for supporting the hardware without Unrestricted Guest (UG) mode (including all the code to fallback on TCG emulation). - not including the Darwin support (which is not yet debugged/tested). - simplifying the initialization by removing the leftovers from the Android specific code, then trimming down the remaining logic. - removing the unused MemoryListener callbacks.
