		Xvisor on Linaro QEMU SMDKC210 Host

This section of readme explains how to build & run Xvisor for SMDKC210 
emulated by QEMU. 

By default, Xvisor for SMDKC210 supports Realview-PB-A8 guest so we will
show how to run Basic Firmware on Realview-PB-A8 guest. For more info 
refer, <xvisor_source>/tests/arm32/realview-pb-a8/basic/README.

Please follow the steps below to build & run Basic Firmware on Realview-PB-A8 
guest with Xvisor running on QEMU SMDKC210 Host:

  [1. Build environment for Xvisor]
  # CROSS_COMPILE=arm-linux-gnueabi-

  [2. GoTo Xvisor source directory]
  # cd <xvisor_source_directory>

  [3. Configure Xvisor with SMDKC210 default settings]
  # make ARCH=arm generic-v7-defconfig

  [4. Build Xvisor]
  # make

  [5. Build Basic Firmware]
  # make -C tests/arm32/realview-pb-a8/basic

  [6. Create disk image for Xvisor]
  # mkdir -p ./build/disk/images/arm32/realview-pb-a8
  # ./build/tools/dtc/dtc -I dts -O dtb -o ./build/disk/images/arm32/realview-pb-a8.dtb ./tests/arm32/realview-pb-a8/realview-pb-a8.dts
  # cp -f ./build/tests/arm32/realview-pb-a8/basic/firmware.bin.patched ./build/disk/images/arm32/realview-pb-a8/firmware.bin
  # cp -f ./tests/arm32/realview-pb-a8/basic/nor_flash.list ./build/disk/images/arm32/realview-pb-a8/nor_flash.list
  # genext2fs -B 1024 -b 16384 -d ./build/disk ./build/disk.img

  [7. Launch QEMU]
  # qemu-system-arm -M smdkc210 -m 256M -display none -serial stdio -kernel build/vmm.bin -dtb build/arch/arm/board/generic/dts/exynos4/smdkc210/one_guest_pb-a8.dtb -initrd build/disk.img

  [8. Kick Guest0 for starting Basic Firmware]
  XVisor# guest kick guest0

  [9. Bind to virtual UART]
  XVisor# vserial bind guest0/uart0

  [10. Say 'hi' to Basic Firmware]
  [guest0/uart0] basic# hi

  [11. Say 'hello' to Basic Firmware]
  [guest0/uart0] basic# hello

  [12. Check various commands of Basic Firmware]
  [guest0/uart0] basic# help

  [13. Enter character seqence 'ESCAPE+x+q" return to Xvisor prompt]
  [guest0/uart0] basic#
