oh I mean like we did in the chrome project.

e.g.
    	device ref pcie_rp8 on
    		# Enable SD Card PCIE 8 using clk 3
    		register "pch_pcie_rp[PCH_RP(8)]" = "{
    			.clk_src = 3,
    			.clk_req = 3,
    			.flags = PCIE_RP_HOTPLUG | PCIE_RP_LTR | PCIE_RP_AER,
    		}"
    	end	#PCIE8 SD card
