Not having a L2 cache controller is a shame, but not an error. Avoid printing an error message if L2 controller initialization returns with ENODEV.
Signed-off-by: Stefan Agner <stefan@agner.ch> --- Hi Russel,
We use a multiplatform kernel for two similar SoC's, one with L2 cache the other without. Maybe silently ignore -ENODEV would be an option too, not sure what is preferred here.
