The Trusted Services uefi-test uses /dev/mem to map its MM communication buffer. The no-strict-devmem.cfg fragment relaxes the mapping restrictions, while CONFIG_DEVMEM controls whether /dev/mem is available. Enable CONFIG_DEVMEM in the same fragment so the test can open /dev/mem and map the communication buffer.
