Not necessarily.  If the vanilla kernel.org (or maybe a paulus tree)
kernel supports the platform you want then you can create a new spec
file called say kernel-2.6.27.spec.in and update it (you could use
kernel-2.6.20.spec.in as a template).

The key is you need also to have (or know from the configs directory) a
kernel configuration that will work for your platform.

Note also that you can also do kernel directory builds (it's an option
under most kernel selection choice lists in ./ltib -m config).  In this
case point you need to simply specify the directory which contains your
kernel source tree.  You still need to know the name (or have) a kernel
config that you want to use.

Is there a particular reason that you can't use the current
kernel-2.6.23-mpc8313erdb_revb available from Freescale? (what new
features do you need)?

It maybe that the kernel for this platform is already available in
mainline (or something better to start your work with).  I'll ask some
people I know and get back to you with an update.
