Peter Maydell 44d79a6bd7 docs: Roll semihosting option information into qemu-options.hx
Currently the per-target documentation for those targets that
implement semihosting includes a bit of text that goes into both the
manual and the manpage about options specific to the target.  This
text is redundant with the earlier generic option description of the
semihosting option produced from qemu-options.hx. To avoid having
to create a lot of stub include files to include into the rST
generated qemu.1 manpage, roll target-specific bits of information
into the qemu-options.hx text, so the user doesn't have to look
in two places for this information.

.. _Xtensa-System-emulator:
Xtensa System emulator
----------------------
Two executables cover simulation of both Xtensa endian options,
``qemu-system-xtensa`` and ``qemu-system-xtensaeb``. Two different
machine types are emulated:
- Xtensa emulator pseudo board \"sim\"
- Avnet LX60/LX110/LX200 board
The sim pseudo board emulation provides an environment similar to one
provided by the proprietary Tensilica ISS. It supports:
- A range of Xtensa CPUs, default is the DC232B
- Console and filesystem access via semihosting calls
The Avnet LX60/LX110/LX200 emulation supports:
- A range of Xtensa CPUs, default is the DC232B
- 16550 UART
- OpenCores 10/100 Mbps Ethernet MAC
