* ssb: Remove SSB_WARN_ON, SSB_BUG_ON and SSB_DEBUGMichael Büsch2018-08-091-9/+0
| | | | | | | | | | | Use the standard WARN_ON instead. If a small kernel is desired, WARN_ON can be disabled globally. Also remove SSB_DEBUG. Besides WARN_ON it only adds a tiny debug check. Include this check unconditionally. Signed-off-by: Michael Buesch <m@bues.ch> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

* ssb: make SSB_PCICORE_HOSTMODE depend on SSB = yRafał Miłecki2018-05-121-1/+1
| | | | | | | | | | | | | | | | SSB_PCICORE_HOSTMODE protects MIPS specific code that calls not exported symbols pcibios_enable_device and register_pci_controller. This code is supposed to be compiled only with ssb builtin. This fixes: ERROR: "pcibios_enable_device" [drivers/ssb/ssb.ko] undefined!

* Revert "ssb: Prevent build of PCI host features in module"Rafał Miłecki2018-05-121-1/+1
| | | | | | | | | | | | | | | | This reverts commit 882164a4a928bcaa53280940436ca476e6b1db8e. Above commit added "SSB = y" dependency to the wrong symbol SSB_DRIVER_PCICORE_POSSIBLE and prevented SSB_DRIVER_PCICORE from being selected when needed. PCI core driver for core running in clienthost mode is important for bus initialization. It's perfectly valid scenario to have ssb built as module and use it with buses on PCI cards. This fixes regression that affected all *module* users with PCI cards.

| * ssb: Do not disable PCI host on non-MipsSven Joachim2018-01-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | After upgrading an old laptop to 4.15-rc9, I found that the eth0 and wlan0 interfaces had disappeared. It turns out that the b43 and b44 drivers require SSB_PCIHOST_POSSIBLE which depends on PCI_DRIVERS_LEGACY, a config option that only exists on Mips.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit d41e6858ba58 ("MIPS: Kconfig: Set default MIPS system type as generic") changed the default MIPS platform to the "generic" platform, which uses PCI_DRIVERS_GENERIC instead of PCI_DRIVERS_LEGACY, various files in drivers/ssb/ have failed to build. This is particularly due to the existence of struct pci_controller being dependent on PCI_DRIVERS_LEGACY since commit c5611df96804 ("MIPS: PCI: Introduce CONFIG_PCI_DRIVERS_LEGACY"), so add that dependency to Kconfig to prevent these files being built for the "generic" platform including all{yes,mod}config builds.

* ssb: pick SoC invariants code from MIPS BCM47xx archRafał Miłecki2015-12-161-1/+1
| | | | | | | | | | | | | There is code in ssb fetching "invariants" that is basically a set of board specific data. Every host requires its own implementation of reading function. In ssb we have support for PCI, PCMCIA & SDIO. For some (historical?) reason code reading "invariants" for SoC was placed in arch code and provided by a callback. This is not needed nowadays, so lets move that into ssb. This way we keep all "invariants" functions in a single module making code cleaner.

* kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes2011-01-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.
