18c2ecf20Sopenharmony_ci* Bus Enumeration by Freescale PCI-X Agent 28c2ecf20Sopenharmony_ci 38c2ecf20Sopenharmony_ciTypically any Freescale PCI-X bridge hardware strapped into Agent mode 48c2ecf20Sopenharmony_ciis prevented from enumerating the bus. The PrPMC form-factor requires 58c2ecf20Sopenharmony_ciall mezzanines to be PCI-X Agents, but one per system may still 68c2ecf20Sopenharmony_cienumerate the bus. 78c2ecf20Sopenharmony_ci 88c2ecf20Sopenharmony_ciThe property defined below will allow a PCI-X bridge to be used for bus 98c2ecf20Sopenharmony_cienumeration despite being strapped into Agent mode. 108c2ecf20Sopenharmony_ci 118c2ecf20Sopenharmony_ciRequired properties: 128c2ecf20Sopenharmony_ci- fsl,pci-agent-force-enum : There is no value associated with this 138c2ecf20Sopenharmony_ci property. The property itself is treated as a boolean. 148c2ecf20Sopenharmony_ci 158c2ecf20Sopenharmony_ciExample: 168c2ecf20Sopenharmony_ci 178c2ecf20Sopenharmony_ci /* PCI-X bridge known to be PrPMC Monarch */ 188c2ecf20Sopenharmony_ci pci0: pci@ef008000 { 198c2ecf20Sopenharmony_ci fsl,pci-agent-force-enum; 208c2ecf20Sopenharmony_ci #interrupt-cells = <1>; 218c2ecf20Sopenharmony_ci #size-cells = <2>; 228c2ecf20Sopenharmony_ci #address-cells = <3>; 238c2ecf20Sopenharmony_ci compatible = "fsl,mpc8540-pcix", "fsl,mpc8540-pci"; 248c2ecf20Sopenharmony_ci device_type = "pci"; 258c2ecf20Sopenharmony_ci ... 268c2ecf20Sopenharmony_ci ... 278c2ecf20Sopenharmony_ci }; 28
