Yes, that's right.

If you selected a "Linux kernel payload" then the Linux kernel is
inside the .rom file and will mount root and start init according to
the Kernel command line option in buildrom. You can find these
options in the buildrom menuconfig:

Payload Configuration -> Desired payload -> Linux kernel
and
Payload Configuration -> Desired payload -> Kernel Configuration -> Kernel command line

It is not needed when you are using buildrom. buildrom downloads it's
own copy of coreboot during the build process.
