[Qemu-devel] Are there any boards with Bay Trail that are supported?

[None None]

I have a Bay Trail Chromebook for which I would like to compile a custom coreboot.  I would like to run this custom coreboot in qemu, before burning it into the flash.  For now I simply read the content of the flash chip (coreboot), and tried running it in qemu using the following command:

qemu-system-x86_64 -M q35 -bios /tmp/flash/bios.bin

I get a crash, almost instantly after running the above command:

qemu: fatal: Trying to execute code outside RAM or ROM at 0x00000000000a0000

Could you please hint me on how I should start approaching this issue?  I somehow suspect that Bay Trail is not yet supported by QEMU.  Also, is it safe to run qemu-system-x86_64, even though the image could be 32 bit?

Thank you.
