>Description:
evbarm and x86 create /dev/nvme* nodes, but aarch64 does not, possibly because of the weird special case for aarch64 in etc/Makefile:

    188 MAKEDEV_MACHINE=${"${MACHINE_CPU}" == "aarch64":?${MACHINE_CPU}:${MACHINE}}
    189 MAKEDEV: ${.CURDIR}/MAKEDEV.awk ${.CURDIR}/MAKEDEV.tmpl \
    190     ${.CURDIR}/etc.${MAKEDEV_MACHINE}/MAKEDEV.conf
    191 	${_MKTARGET_CREATE}
    192 	MACHINE=${MAKEDEV_MACHINE:Q} MACHINE_ARCH=${MACHINE_ARCH:Q} \
    193 	    NETBSDSRCDIR=${NETBSDSRCDIR:Q} \
    194 	    ${TOOL_AWK} -f ${.CURDIR}/MAKEDEV.awk ${.CURDIR}/MAKEDEV.tmpl \
    195 	    > ${.TARGET}

https://nxr.netbsd.org/xref/src/etc/Makefile?r=1.469#188
>How-To-Repeat:
nvmectl devlist
>Fix:
Copy & paste the nvme lines from etc.evbarm/MAKEDEV.conf to etc.aarch64/MAKEDEV.conf.
