Merge patch series "m68k: Add support for QEMU virt machine"
Kuan-Wei Chiu <[email protected]> says:
Add support for the QEMU 'virt' machine on the m68k architecture. The
QEMU virt machine models a generic system utilizing Goldfish virtual
peripherals and is capable of emulating various classic 68k CPUs.
Currently, U-Boot's m68k architecture support focuses on ColdFire
variants. This series expands support to include the classic M680x0
architecture, implementing the necessary exception vectors, startup
code, and a bootinfo parser compatible with the QEMU interface.
Drivers for Goldfish peripherals (TTY, Timer, RTC) and the QEMU
Virtual System Controller (sysreset) are also added to enable serial
console, timekeeping, and system reset functionality.
The implementation has been verified on QEMU targeting the M68040 CPU,
confirming successful hardware initialization and boot to the U-Boot
command shell. Additionally, the CI configuration was verified locally
using gitlab-ci-local "qemu_m68k_virt test.py", resulting in
PASS qemu_m68k_virt test.py.
