Add support for the QEMU 'virt' machine on the m68k architecture. This board emulates a generic machine based on the Motorola 68040 CPU equipped with Goldfish virtual peripherals. Introduce the necessary board configuration and initialization infrastructure. The implementation includes logic to parse the QEMU bootinfo interface, enabling dynamic detection of system RAM size to adapt to the virtual machine's configuration. Enable the Goldfish TTY driver for serial console output. Additionally, enable Goldfish RTC and timer drivers to support real-time clock functionality and nanosecond-resolution delays. Include comprehensive documentation covering build instructions and usage examples.
