I'm trying to enable SATA hotplug (in OS) feature on my board. And one of my
attempts is to run AHCI option rom from original BIOS.

I use coreboot/seabios bundle with seabios responsible for option ROM
execution. And I stuck with a problem, that seabios doesn't want to run ROM
on SATA controllers cause of pci->have_driver check:




        // Find and deploy PCI roms.

        struct pci_device *pci;

        foreachpci(pci) {

            if (pci->class == PCI_CLASS_DISPLAY_VGA || pci->have_driver)


            init_pcirom(pci, 0, sources);








// Handle controllers on an ATA PCI device.

static void

init_pciata(struct pci_device *pci, u8 prog_if)


    pci->have_driver = 1;





So, what is a proper way to run roms like AHCI on SATA controllers?

(in my case SATA controller is embedded device in southbridge)
