boards: qemu_arc: Enable networking via SLIP (serial port) The simplest way of getting networking to work on really tiny embedded system is to use an extra serial port as an interface to external world with help of a SLIP, see https://en.wikipedia.org/wiki/Serial_Line_Internet_Protocol. The catch is on a deeply embedded system we most likely won't see an Ethernet MAC in the system as it might be as large ans as complex as the CPU itself so there's no point in adding it. Moreover it will require support in drivers, which are very hardware specific (not only IP-block specific, but also need to take care of all the quirks made in this particular instance and platform). But with SLIP we may use existing serial port of the board which already has all the needed support and with a platform-agnotic code of SLIP we may have usable networking on both simulators & real HW boards. And that's what we do in Zephyr. Now we teach ARC's QEMU platform to do so as well. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

ARC: Add support for basic QEMU platform for ARC EM & HS Now when we're finally ready to open QEMU port for ARC we introduce the first ever platform it supports and in fact does that quite well - Zephyr RTOS. For now we only offer support of basic EM & HS code execution, built-in timers, interrupt controller and set of very simple peripherals: DW UART & optionally MMIO Virtio devices.
