Reviving the Classics: Porting U-Boot to QEMU m68k virt

While QEMU has long provided robust emulation for the classic Motorola 680x0 family, including the generic virt machine, the widely adopted open-source bootloader, U-Boot, had seen its m68k architecture support become almost entirely focused on modern ColdFire variants. Consequently, classic m68k CPUs lacked a functional, generic target within the U-Boot upstream.

This talk explores the technical journey of bridging that gap by bringing U-Boot to the QEMU m68k virt machine. We will dive into the architectural bring-up, the implementation of Goldfish peripheral drivers, and the intricacies of parsing bootinfo.
