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/.
Changes since v1:
- rename all HAS_* Kconfig symbols to HAVE_*
- drop the CONFIG_PCI_QSPAN option entirely
- drop duplicate select from powerpc
- restore missing selection of PCI_MSI for riscv
- update x86 and riscv defconfigs to include PCI
- actually inclue drivers/eisa/Kconfig
- adjust some captilizations

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

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 HAVE_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 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.

Thanks for the update!
Please use "git format-patch -v<N> --cover" to prepare patch series
for sending with git-send-email.
"-v<N>" to prefix all patches with version number <N>,
"--cover" to have a "[PATCH 0/<M>]" prefix in the cover letter.
Thanks!

I doubt this.
arch/arm/Kconfig previously did not include
driver/eisa/Kconfig.
No ARM platform enabled CONFIG_EISA either.

Just in case, could you double-check these?
PCI_ENDPOINT
PCI_ENDPOINT_CONFIGFS
PCI_EPF_TEST
Previously, architecture without "source drivers/pci/Kconfig"
could not enable PCI_ENDPOINT.
Now, any architecture can enable it
regardless of its actual PCI availability
because PCI_ENDPOINT is only guarded by HAS_DMA.
We could add 'depends on HAVE_PCI' or something
to guard it to avoid changing the logic.
config PCI_ENDPOINT
bool "PCI Endpoint Support"
depends on HAVE_PCI # Is this correct ??
depends on HAS_DMA
or better to have 'depends on PCI' ?
PCI ML is also CC'ed, so comments are appreciated.

This change doesn't make sense as there's no PCI hardware in the Xtensa ISS.

We had that discussion before and I strongly disagree with messing

It does not depend on the normal PCI support, so I don't think this
is the right thing to do.

But it did offer the EISA option. I guess I can remove this in

Can you please clarify what exactly that would mess up?
Documentation/process/submitting-patches.rst even mentions the tags
to put in "[PATCH <tag>]"?
Without this:
- It's hard to visually match your untagged cover letter with the
actual patches,
- Your individual patches lack the version info, so people cannot see which
version review comments in an email reply apply to.
Thanks!

It makes the already limited space in the subject line even shorted
(or harder to read depending on which way you go) for absolutely not
good reason.

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
show I can keep you in the loop.

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

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.
