Adding qemu as a submodule of KVMFORNFV
This Patch includes the changes to add qemu as a submodule to kvmfornfv repo and make use of the updated latest qemu for the execution of all testcase Change-Id: I1280af507a857675c7f81d30c95255635667bdd7 Signed-off-by:RajithaY<rajithax.yerrumsetty@intel.com>

-The support for multiple serial interfaces as implemented is mainly
-intended to allow for modem dial-in / dial-out while still being able
-to use a serial console on a (different) serial port.
-
-MPC8XX Specific
-===============
-At the moment, the ports must be split on a SMC and a SCC port on a
-8xx processor; other configurations are not (yet) supported.
-
-Support for hardware handshake has not been implemented yet (but is
-in the works).
-
-*) The default console depends on the keys pressed:
- - SMC if keys not pressed (modem not enabled)
- - SCC if keys pressed (modem enabled)
-
-*) The console can be switched to SCC by any of the following commands:
-
- setenv stdout serial_scc
- setenv stdin serial_scc
- setenv stderr serial_scc
-
-*) The console can be switched to SMC by any of the following commands:
-
- setenv stdout serial_smc
- setenv stdin serial_smc
- setenv stderr serial_smc
-
-*) If a file descriptor is set to "serial" then the current serial device
-will be used which, in turn, can be switched by above commands.
-
-*) The baudrate is the same for all serial devices. But it can be switched
-just after switching the console:
-
- setenv sout serial_scc; setenv baudrate 38400
-
-After that press 'enter' at the SCC console. Note that baudrates <38400
-are not allowed on LWMON with watchdog enabled (see CONFIG_SYS_BAUDRATE_TABLE in
-include/configs/lwmon.h).
-
-
-PPC4XX Specific
-===============
-*) The default console is UART0
-
-*) The console can be switched to UART1 by any of the following commands:
- setenv stdout serial1
- setenv stderr serial1
- setenv stdin serial1
-
-*) The console can be switched to UART0 by any of the following commands:
- setenv stdout serial0
- setenv stderr serial0
- setenv stdin serial0
-
-MPC5xxx Specific
-================
-
-Up to two PSCs can be used as console.
-
-Support for hardware handshake has not been implemented yet.
-
-*) The first (default) console port is defined by:
- #define CONFIG_PSC_CONSOLE <PSC number>
-
-*) The second (alternative) console port is defined by:
- #define CONFIG_PSC_CONSOLE2 <PSC number>
-
-*) Commands to switch to the second console:
- setenv stdout serial1
- setenv stderr serial1
- setenv stdin serial1
-
-*) Commands to switch to the first console:
- setenv stdout serial0
- setenv stderr serial0
- setenv stdin serial0
-
-*) If a file descriptor is set to "serial" then the
- current serial device will be used.
