From: Arnd Bergmann <arnd@arndb.de>
There are six variants of the cpsw driver, sharing various parts of
the code: davinci-emac, cpsw, cpsw-switchdev, netcp, netcp_ethss and
am65-cpsw-nuss.
I noticed that this means some files can be linked into more than
one loadable module, or even part of vmlinux but also linked into
a loadable module, both of which mess up assumptions of the build
system, and causes warnings:
scripts/Makefile.build:279: cpsw_ale.o is added to multiple modules: ti-am65-cpsw-nuss ti_cpsw ti_cpsw_new
scripts/Makefile.build:279: cpsw_priv.o is added to multiple modules: ti_cpsw ti_cpsw_new
scripts/Makefile.build:279: cpsw_sl.o is added to multiple modules: ti-am65-cpsw-nuss ti_cpsw ti_cpsw_new
scripts/Makefile.build:279: cpsw_ethtool.o is added to multiple modules: ti_cpsw ti_cpsw_new
scripts/Makefile.build:279: davinci_cpdma.o is added to multiple modules: ti_cpsw ti_cpsw_new ti_davinci_emac
Change this back to having separate modules for each portion that
can be linked standalone, exporting symbols as needed:
- ti-cpsw-common.ko now contains both cpsw-common.o and
davinci_cpdma.o as they are always used together
- ti-cpsw-priv.ko contains cpsw_priv.o, cpsw_sl.o and cpsw_ethtool.o,
which are the core of the cpsw and cpsw-new drivers.
- ti-cpsw-sl.ko contains the cpsw-sl.o object and is used on
ti-am65-cpsw-nuss.ko in addition to the two other cpsw variants.
- ti-cpsw-ale.o is the one standalone module that is used by all
except davinci_emac.
Each of these will be built-in if any of its users are built-in, otherwise
it's a loadable module if there is at least one module using it. I did
not bring back the separate Kconfig symbols for this, but just handle
it using Makefile logic.
Note: ideally this is something that Kbuild complains about, but usually
we just notice when something using THIS_MODULE misbehaves in a way that
a user notices.
Fixes: 99f6297182729 ("net: ethernet: ti: cpsw: drop TI_DAVINCI_CPDMA config option")

v2: rebase on top of v6.9-rc
v3: rebase on top of v7.0-rc
v4: resend together with soft_reset() change, which is a dependency
