[PATCH v2 00/14] [net-next] drivers/net/Space.c cleanup

[PATCH v2 00/14] [net-next] drivers/net/Space.c cleanup

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

I discovered that there are still a couple of drivers that rely on
beiong statically initialized from drivers/net/Space.c the way
we did in the last century. As it turns out, there are a couple
of simplifications that can be made here, as well as some minor
bugfixes.

There are four classes of drivers that use this:

- most 10mbit ISA bus ethernet drivers (and one 100mbit one)
- both ISA localtalk drivers
- several m68k ethernet drivers
- one obsolete WAN driver

I found that the drivers using in arch/m68k/ don't actually benefit
from being probed this way as they do not rely on the netdev= command
line arguments, they have simply never been changed to work like a
modern driver.

I had previously sent a patch to remove the sbni/granch driver, and
there were no objections to this patch but forgot to resend it after
some discussion about another patch in the same series.

For the ISA drivers, there is usually no way to probe multiple devices
at boot time other than the netdev= arguments, so all that logic is left
in place for the moment, but centralized in a single file that only gets
included in the kernel build if one or more of the drivers are built-in.

I'm also changing the old-style init_module() functions in these drivers
to static functions with a module_init() annotation, to more closely
resemble modern drivers. These are the last drivers in the kernel to
still use init_module/cleanup_module, removing those may enable future
cleanups to the module loading process.

[PATCH v2 01/14] [net-next] bcmgenet: remove call to netdev_boot_setup_check

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The driver has never used the netdev->{irq,base_addr,mem_start}
members, so this call is completely unnecessary.

[PATCH v2 02/14] [net-next] natsemi: sonic: stop calling netdev_boot_setup_check

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The data from the kernel command line is no longer used since the
probe function gets it from the platform device resources instead.

The jazz version was changed to be like this in 2007, the xtensa
version apparently copied the code from there.

[PATCH v2 03/14] [net-next] appletalk: ltpc: remove static probing

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

This driver never relies on the netdev_boot_setup_check()
to get its configuration, so it can just as well do its
own probing all the time.

[PATCH v2 05/14] [net-next] cs89x0: rework driver configuration

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

There are two drivers in the cs89x0 file, with the CONFIG_CS89x0_PLATFORM
symbol deciding which one is getting built. This is somewhat confusing
and makes it more likely ton configure a driver that works nowhere.

Split up the Kconfig option into separate ISA and PLATFORM drivers,
with the ISA symbol explicitly connecting to the static probing in
drivers/net/Space.c

The two drivers are still mutually incompatible at compile time,
which could be lifted by splitting them into multiple files,
but in practice this will make no difference.

The platform driver can now be enabled for compile-testing on
non-ARM machines.

[PATCH v2 06/14] [net-next] m68k: remove legacy probing

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

There are six m68k specific drivers that use the legacy probe method
in drivers/net/Space.c. However, all of these only support a single
device, and they completely ignore the command line settings from
netdev_boot_setup_check, so there is really no point at all.

Aside from sun3_82586, these already have a module_init function that
can be used for built-in mode as well, simply by removing the #ifdef.

Note that the 82596 driver was previously used on ISA as well, but
that got dropped long ago.

[PATCH v2 07/14] [net-next] ax88796: export ax_NS8390_init() hook

[Arnd Bergmann]

From: Michael Schmitz <schmitzmic@gmail.com>

The block I/O code for the new X-Surf 100 ax88796 driver needs
ax_NS8390_init() for error fixup in its block_output function.

Export this static function through the ax_NS8390_reinit()
wrapper so we can lose the lib8380.c include in the X-Surf 100
driver.

[arnd: add the declaration in the header to avoid a
 -Wmissing-prototypes warning]

[PATCH v2 08/14] [net-next] xsurf100: drop include of lib8390.c

[Arnd Bergmann]

From: Michael Schmitz <schmitzmic@gmail.com>

Now that ax88796.c exports the ax_NS8390_reinit() symbol, we can
include 8390.h instead of lib8390.c, avoiding duplication of that
function and killing a few compile warnings in the bargain.

Obviously the second change shouldn't have been part of this patch,
and no one noticed.  Patch sent.

[PATCH v2 09/14] [net-next] move netdev_boot_setup into Space.c

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

This is now only used by a handful of old ISA drivers,
and can be moved into the file they already all depend on.

[PATCH v2 10/14] [net-next] make legacy ISA probe optional

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

There are very few ISA drivers left that rely on the static probing from
drivers/net/Space.o. Make them all select a new CONFIG_NETDEV_LEGACY_INIT
symbol, and drop the entire probe logic when that is disabled.

The 9 drivers that are called from Space.c are the same set that
calls netdev_boot_setup_check().

My rbtx4927 build log says:

defined but not used [-Wunused-function]

The network still works fine (nfsroot).

Sorry about that. I made the patch when you first reported it, and I was
sure I had sent it, but apparently not. Sent it now.

[PATCH v2 11/14] [net-next] wan: remove stale Kconfig entries

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The dscc4 driver was removed in 2019 but these Kconfig entries remain,
so remove them as well.

[PATCH v2 12/14] [net-next] wan: remove sbni/granch driver

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

The driver was merged in 1999 and has only ever seen treewide cleanups
since then, with no indication whatsoever that anyone has actually
had access to hardware for testing the patches.

From the information in the link below, it appears that the hardware
is for some leased line system in Russia that has since been
discontinued, and useless without any remote end to connect to.

As the driver still feels like a Linux-2.2 era artifact today, it
appears that the best way forward is to just delete it.

Link: https://www.tms.ru/%D0%90%D0%B4%D0%B0%D0%BF%D1%82%D0%B5%D1%80_%D0%B4%D0%BB%D1%8F_%D0%B2%D1%8B%D0%B4%D0%B5%D0%BB%D0%B5%D0%BD%D0%BD%D1%8B%D1%85_%D0%BB%D0%B8%D0%BD%D0%B8%D0%B9_Granch_SBNI12-10

[PATCH v2 13/14] [net-next] wan: hostess_sv11: use module_init/module_exit helpers

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

This is one of very few drivers using the old init_module/cleanup_module
function names. Change it over to the modern method.

[PATCH v2 14/14] [net-next] ethernet: isa: convert to module_init/module_exit

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

There are a couple of ISA ethernet drivers that use the old
init_module/cleanup_module function names for the main entry
points, nothing else uses those any more.

Change them to the documented method with module_init()
and module_exit() markers next to static functions.
