move bus (PCI, PCMCIA, EISA, rapdio) config to drivers/ v4

move bus (PCI, PCMCIA, EISA, rapdio) config to drivers/ v4

[Christoph Hellwig]

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 v3:
 - drop the patches already merged
 - fix a typo in the PCI help text
 - split the always enable PCI on alpha change into a separate patch
 - remove the mips HT_PCI symbol
 - add a new FORCE_PCI symbol to easily allow selecting PCI support
 - new patch to consolidate PCI_DOMAINS
 - new patch to consolidate PCI_SYSCALL

Changes since v2:
 - depend on HAVE_PCI for PCIe endpoint code
 - fix some commit message typos
 - remove CONFIG_PCI from xtensa iss defconfig
 - drop EISA support from arm
 - clean up EISA selection for alpha

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

[PATCH 1/9] arm: remove EISA kconfig option

[Christoph Hellwig]

No arm config enables EISA, and arm does not include drivers/eisa/Kconfig
which provides support for things like PCI to EISA bridges, so it is most
likely dead.

As I said before, this is absolutely dead.

Only the difference between arch/powerpc/Kconfig and arch/arm/Kconfig
is the presence of ---help--- property.


I squashed this to "eisa: consolidate EISA ..."

I do not understand this patch
because alpha already enables PCI forcibly.

'No prompt' + 'default y' means always on.

config PCI
        bool
        depends on !ALPHA_JENSEN
        select GENERIC_PCI_IOMAP
        default y


I squashed this patch to "PCI: consolidate PCI config entry ..."
because you will replace it to FORCE_PCI anyway.

[PATCH 3/9] MIPS: remove the HT_PCI config option

[Christoph Hellwig]

This option is always selected from LOONGSON_MACH3X.  Switch to just
seleting PCI from that option and definining LOONGSON_PCIIO_BASE based
on CONFIG_LOONGSON_MACH3X.

[PATCH 3/9] MIPS: remove the HT_PCI config option

[Christoph Hellwig]

This option is always selected from LOONGSON_MACH3X.  Switch to just
seleting PCI from that option and definining LOONGSON_PCIIO_BASE based
on CONFIG_LOONGSON_MACH3X.

[PATCH 4/9] PCI: consolidate PCI config entry in drivers/pci

[Christoph Hellwig]

There is no good reason to duplicate the PCI menu in every architecture.
Instead provide a selectable HAVE_PCI symbol that indicates availability
of PCI support, and a FORCE_PCI symbol to for PCI on and the handle the
rest in drivers/pci.

[PATCH 4/9] PCI: consolidate PCI config entry in drivers/pci

[Christoph Hellwig]

There is no good reason to duplicate the PCI menu in every architecture.
Instead provide a selectable HAVE_PCI symbol that indicates availability
of PCI support, and a FORCE_PCI symbol to for PCI on and the handle the
rest in drivers/pci.

[PATCH 4/9] PCI: consolidate PCI config entry in drivers/pci

[Christoph Hellwig]

There is no good reason to duplicate the PCI menu in every architecture.
Instead provide a selectable HAVE_PCI symbol that indicates availability
of PCI support, and a FORCE_PCI symbol to for PCI on and the handle the
rest in drivers/pci.

[PATCH 5/9] PCI: consolidate the PCI_DOMAINS and PCI_DOMAINS_GENERIC config options

[Christoph Hellwig]

Move the definitions to drivers/pci and let the architectures select
them.  Two small differences to before: PCI_DOMAINS_GENERIC now selects
PCI_DOMAINS, cutting down the churn for modern architectures.  As the
only architectured arm did previously also offer PCI_DOMAINS as a user
visible choice in addition to selecting it from the relevant configs,
this is gone now.

PCI_DOMAINS, cutting down the churn for modern architectures.  As the

visible choice in addition to selecting it from the relevant configs,
this is gone now.

[PATCH 5/9] PCI: consolidate the PCI_DOMAINS and PCI_DOMAINS_GENERIC config options

[Christoph Hellwig]

Move the definitions to drivers/pci and let the architectures select
them.  Two small differences to before: PCI_DOMAINS_GENERIC now selects
PCI_DOMAINS, cutting down the churn for modern architectures.  As the
only architectured arm did previously also offer PCI_DOMAINS as a user
visible choice in addition to selecting it from the relevant configs,
this is gone now.

I reordered this so it 'bool' comes first.

config PCI_DOMAINS
       bool
       depends on PCI


config PCI_DOMAINS_GENERIC
       bool
       depends on PCI
       select PCI_DOMAINS


Of course, it is just a matter of slight taste.
I just wanted the code to look consistent.

[PATCH 7/9] pcmcia: allow PCMCIA support independent of the architecture

[Christoph Hellwig]

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.

[PATCH 8/9] rapidio: consolidate RAPIDIO config entry in drivers/rapidio

[Christoph Hellwig]

There is no good reason to duplicate the RAPIDIO menu in various
architectures.  Instead provide a selectable HAVE_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.
