Hi,
I noticed that u-boot.rom does not boot in qemu-system-x86_64 (8.2.4) with KVM accelerator:
builder@x86_64:~/RPM/BUILD/u-boot-qemu-2024.07$ qemu-system-x86_64 -M accel=kvm -nographic -bios ./u-boot.rom
U-Boot SPL 2024.07 (Jul 04 2024 - 09:26:24 +0000) int_exception_handler() Exception 13 while executing option rom <hangs>
The same rom with `-M accel=tcg` boots OK[1].
Thanks,
