I Compiled Coreboot with Seabios and Tianocore payload on Baytrail SoC. I want to use a [PCIe bridge][3] to convert a PCIE-x1 to 2 PCIE-X1 connectors but booting FreeBSD won't show any active bridge.
The [Baytrail SoC documentation][1] states that a register called [SLCTL_SLSTS][2] should be set in order to activate the bridge support but I don't know how to set such flag on coreboot.
- Is it possible to use PCIe bridge on Baytrail SoCs? - How one can add bridge support to coreboot if possible?
