At least, I assume that's the equivalent file. :-)

 AIUI, config.txt sets up the Pi, cmdline.txt furnishes
runtime arguments to the kernel when that kernel is
linux. If this isn't true somebody please correct me!
 

I've just looked at what's on mine:
root@kirk:/ # df /boot/msdos/

/dev/msdosfs/MSDOSBOOT     51096 25084 26012    49%    /boot/msdos

bcm2710-rpi-2-b.dtb             dtb fixup_cd.dat                    start4cd.elf                    u-boot.bin
So I seem to be running with no cmdline.txt. Boots happily off the attached usb drive, no sdcard.
But I stand corrected.
