      3 RX System emulator
      4 --------------------
      5 
      6 Use the executable ``qemu-system-rx`` to simulate RX target (GDB simulator).
      7 This target emulated following devices.
      8 
      9 -  R5F562N8 MCU
     10 
     11    -  On-chip memory (ROM 512KB, RAM 96KB)
     12    -  Interrupt Control Unit (ICUa)
     13    -  8Bit Timer x 1CH (TMR0,1)
     14    -  Compare Match Timer x 2CH (CMT0,1)
     15    -  Serial Communication Interface x 1CH (SCI0)
     16 
     17 -  External memory 16MByte

     19 Example of ``qemu-system-rx`` usage for RX is shown below:
     20 
     21 Download ``<u-boot_image_file>`` from
     22 https://osdn.net/users/ysato/pf/qemu/dl/u-boot.bin.gz
     23 
     24 Start emulation of rx-virt::
     25   qemu-system-rx -M gdbsim-r5f562n8 -bios <u-boot_image_file>
     26 
     27 Download ``kernel_image_file`` from
     28 https://osdn.net/users/ysato/pf/qemu/dl/zImage
     29 
     30 Download ``device_tree_blob`` from
     31 https://osdn.net/users/ysato/pf/qemu/dl/rx-virt.dtb
     32 
     33 Start emulation of rx-virt::
     34   qemu-system-rx -M gdbsim-r5f562n8 \
     35       -kernel <kernel_image_file> -dtb <device_tree_blob> \
     36       -append "earlycon"
