# Platform-specific glue layers go here
#
# NOTICE: Make sure your glue layer doesn't depend on anything
# which is arch-specific and that it compiles on all situations.
#
# We want to keep this requirement in order to be able to compile
# the entire driver (with all its glue layers) on several architectures
# and make sure it compiles fine. This will also help with allmodconfig
# and allyesconfig builds.
#
# The only exception is the PCI glue layer, but that's only because
# PCI doesn't provide nops if CONFIG_PCI isn't enabled.
