# The brcmfmac driver can be built with support for different system buses
# (SDIO, and simulated-firmware), and different configurations will require
# different support.  To facilitate consolidating all the potentially messy
# conditional compilation in one place, "bus.cc" is conditionally compiled based
# on the values of the preprocessor #defines:
#
# * CONFIG_BRCMFMAC_SDIO
# * CONFIG_BRCMFMAC_SIM
#
# These #defines are applied as public_configs entries on the targets,
# respectively:
#
# * :sdio
# * :sim
#
# Thus a target that depends on one of the above targets, can include "bus.cc"
# in its sources and will then conditionally compile it with the set of
# preprocessor #defines set by the targets it depends on.
#
# See the targets ":driver_module" and ":driver_test" to see how this is done.
