When booting Linux on FVP RevC, Linux reports the following error: ACPI: IORT: [Firmware Bug]: Root complex missing memory address limit
This issue is due to the RC Address Limit not being configured in the configuration manager for the platform. The default model parameter is configured to 32, so set this in the configuration manager, fixing the error.
