Hi all,
currently every architecture that wants to provide on of the common
periphal busses needs to add some boilerplate code and include the
right Kconfig files. This series instead just selects the presence
(when needed) and then handles everything in the bus-specific
Kconfig file under drivers/.

We plan to enable building the pcmcia core and drivers, and the
non-prefixed PCMCIA name clashes with some arch headers.

The way how CONFIG_PCI_QSPAN selects the CONFIG_PCI default is highly
unusual and gets in the way of moving CONFIG_PCI into
drivers/pci/Kconfig. Simplify it by just having it depend on
CONFIG_PCI.

Various powerpc boards select the PCI_MSI config option without selecting
PCI, resulting in potentially not compilable configurations if the by
default enabled PCI option is disabled. Explicitly select PCI to ensure
we always have valid configs.

There is no good reason to duplicate the PCI menu in every architecture.
Instead provide a selectable HAS_PCI symbol that indicates availability
of PCI support and the handle the rest in drivers/pci.
Note that for powerpc we now select HAS_PCI globally instead of the
convoluted mess of conditional or or non-conditional support per board,
similar to what we do e.g. on x86. For alpha PCI is selected for the
non-jensen configs as it was the default before, and a lot of code does
not compile without PCI enabled. On other architectures with limited
PCI support that wasn't as complicated I've left the selection as-is.

There is no good reason to duplicate the PCI menu in every architecture.
Instead provide a selectable HAS_PCI symbol that indicates availability
of PCI support and the handle the rest in drivers/pci.
Note that for powerpc we now select HAS_PCI globally instead of the
convoluted mess of conditional or or non-conditional support per board,
similar to what we do e.g. on x86. For alpha PCI is selected for the
non-jensen configs as it was the default before, and a lot of code does
not compile without PCI enabled. On other architectures with limited
PCI support that wasn't as complicated I've left the selection as-is.

PCI or a specific SOC.

There is nothing architecture specific in the PCMCIA core, so allow
building it everywhere. The actual host controllers will depend on ISA,
PCI or a specific SOC.

There is no good reason to duplicate the RAPIDIO menu in various
architectures. Instead provide a selectable HAS_RAPIDIO symbol
that indicates native availability of RAPIDIO support and the handle
the rest in drivers/pci. This also means we now provide support
for PCI(e) to Rapidio bridges for every architecture instead of a
limited subset.

Let architectures opt into EISA support by selecting HAS_EISA and
handle everything else in drivers/eisa.

Looks good to me, though I'm interested on any subtle (build) breakage when
this gets exposure in -next. Will you push this patch upstream directly, or
should it go in via the pcmcia tree? If it is the former, feel free to add

The patches in the series depend on each other (just in terms of
context). I suspect the best would be to get it into the kbuild tree.
It has survived the build bot, which found some interesting issues in
the other patches (as well as the !UML dependency), but if more issues

The patches in the series depend on each other (just in terms of
context). I suspect the best would be to get it into the kbuild tree.
It has survived the build bot, which found some interesting issues in
the other patches (as well as the !UML dependency), but if more issues

masahiro@pug:~/ref/linux$ git grep PCI_QSPAN
arch/powerpc/Kconfig: default PCI_QSPAN if PPC_8xx
arch/powerpc/Kconfig:config PCI_QSPAN
With your patch, PCI_QSPAN will become
a dead config option.
How about removing it entirely?

I think HAVE_ is a preferred prefix in this case according to this doc:
https://github.com/masahir0y/linux/blob/v4.19-rc4/Documentation/kbuild/kconfig-language.txt#L448
It is true we have some options with HAS_ prefix,
but the majority is HAVE_.

If you do this for entire powerpc,
the other 'select HAS_PCI' addtions to
arch/powerpc/platforms/*/Kconfig look redundant.

I think most of people want to use PCI for x86,
and this change will make people upset.

How about HAVE_EISA ?
You forgot to add

Better to add CONFIG_EISA=y to arch/alpha/defconfig
to not flip the default?

Yes. Alternatively we could add a new ARCH_PCI_DEFAULT symbol,
that architectures could select if they want PCI by default. Does
anyone thing this is a good idea?

No, I do not want to see such an ugly config option.
Instead, you can use 'imply' keyword to set the default y.
config X86
...
imply PCI
But, personally, I'd like the defconfig files updated.

Thanks for doing this. It's a great cleanup. I know you have a few
things you're cleaning up, but add my:

Thanks for doing this. It's a great cleanup. I know you have a few
things you're cleaning up, but add my:

I'd like to see "kconfig:" only for patches

Sorry, I missed this for v2. Will fix it up for the next version

There is no good reason to duplicate the RAPIDIO menu in various
architectures. Instead provide a selectable HAS_RAPIDIO symbol
that indicates native availability of RAPIDIO support and the handle
the rest in drivers/pci. This also means we now provide support
for PCI(e) to Rapidio bridges for every architecture instead of a
limited subset.

There is no good reason to duplicate the RAPIDIO menu in various
architectures. Instead provide a selectable HAS_RAPIDIO symbol
that indicates native availability of RAPIDIO support and the handle
the rest in drivers/pci. This also means we now provide support
for PCI(e) to Rapidio bridges for every architecture instead of a
limited subset.
