# **Note!** It's important that this library not depend on the
# <lib/mmio/mmio.h> header at all, so it doesn't need to have
# "$zx/system/dev/lib/mmio:headers" here. The hwreg library can be used
# with either the real mmio library ($zx/system/dev/lib/mmio) or with the
# mock for testing ($zx/system/dev/lib/mock-mmio-reg). The mock library
# provides an alternate <lib/mmio/mmio.h> implementation. If anything
# that wants to use the mock library also winds up with the real library
# in its deps (indirectly via public_deps in libraries like this) then
# it's hard to make sure the library paths put the mock library first.
# So it's better to simply avoid having the real library in the deps at
# all. But this means that this library's headers must be maintained so
# that they can be used along with either <lib/mmio/mmio.h>
# implementation without actually including *either* header at all.
