Masahiro Yamada 53d82096b6 qemu_arm_versatile_nommu: switch to in-kernel defconfig + fragment
This platform has its own kernel defconfig in Buildroot, but we cannot
get quick idea about how much it diverged from the in-kernel defconfig.

Let's use the upstream arch/arm/config/versatile_defconfig as a base,
and maintain the diff as a merge-config fragment. The same .config is
still generated based on the 5.10.7 kernel.

The diff is quite big, but this is a good start-point for cleanups.
Follow-up works can drop diff lines unless we find a good reason for
divergence.

Run the emulation with:

  qemu-system-arm -M versatilepb -kernel output/images/zImage -dtb output/images/versatile-pb.dtb -drive file=output/images/rootfs.ext2,if=scsi,format=raw -append "rootwait root=/dev/sda console=ttyAMA0,115200" -serial stdio -net nic,model=rtl8139 -net user # qemu_arm_versatile_defconfig

Or for the noMMU emulation:

  qemu-system-arm -M versatilepb -kernel output/images/zImage -dtb output/images/versatile-pb.dtb -append "console=ttyAMA0,115200" -serial stdio -net user -net nic,model=smc91c111 # qemu_arm_versatile_nommu_defconfig

The login prompt will appear in the terminal that started Qemu. The
graphical window is the framebuffer.
