Without this ``iomem=relaxed`` kernel parameter, the generated board XML is essentially the same as having ``--basic`` when executing the board inspector, i.e. the ACPI namespace will not be parsed. The generated board XML may still work, but some functionality (e.g. passthru of TPM and other PCI devices that need INTx) will no longer work due to lack of hardware information.
