Hi, Rafael Could you please help to review this patch? This is a small change to add ACPI_SIG_IORT to table_sigs[]. Loading IORT table from initrd is very useful to debug SMMU node/device probe, MSI allocation, stream id translation and verifying IORT table from firmware. So, I add this.
Thanks Shunyong.
