[SeaBIOS] Marvell 88SE9230 passthrough in KVM takes long time to boot

I'm passing through a Marvell 88SE9230 card to a KVM guest under
Ubuntu 18.04. The card is a Sata controller with 4 ports.
The option rom of the Marvell 88SE9230 card shows on a normal boot a
bios screen. When pressing CTRL-m quick enough, you  can interrupt the
bootprocess and enter a menue wherer you can define raid

When booting seabios inside KVM the bootprocess is very slow.
There is a 1 min holdtime where the cpu is about 30%. The screen is
black with only the seabios version string shown. I suspect that
the passed-through Marvell 88SE9230 cards option roms causes this
Maybe the scanning for option rom cause the slow bootprocess?

In the seabios boot case no bios menue is shown, after
around 1 min the boot continues.

Is it possible to disable the options rom processing? Is there some
documentation about this (How can I configure it for Ubuntu) ?

// Greetings Konrad
