* powerpc: Remove platforms/wsp and associated piecesMichael Ellerman2014-06-11
| | | | | | | | | | | | | __attribute__ ((unused)) WSP is the last user of CONFIG_PPC_A2, so we remove that as well. Although CONFIG_PPC_ICSWX still exists, it's no longer selectable for any Book3E platform, so we can remove the code in mmu-book3e.h that depended on it.

* powerpc: Add skeleton PowerNV platformBenjamin Herrenschmidt2011-09-20
| | | | | | | | | | | | | | | | This adds a skeletton for the new Power "Non Virtualized" platform which will be used by machines supporting running without an hypervisor, for example in order to run KVM. These machines will be using a new firmware called OPAL for which the support will be provided by later patches. The PowerNV platform is intended to be also usable under the BML environment used internally for early CPU bringup which is why the code also supports using RTAS instead of OPAL in various places.

* powerpc: Add WSP platformDavid Gibson2011-05-05

* powerpc: Add configurable -Werror for arch/powerpcMichael Ellerman2009-06-16
| | | | | | | | | | | | | | | | | | | | Add the option to build the code under arch/powerpc with -Werror. The intention is to make it harder for people to inadvertantly introduce warnings in the arch/powerpc code. It needs to be configurable so that if a warning is introduced, people can easily work around it while it's being fixed. The option is a negative, ie. don't enable -Werror, so that it will be turned on for allyes and allmodconfig builds. The default is n, in the hope that developers will build with -Werror, that will probably lead to some build breaks, I am prepared to be flamed. It's not enabled for math-emu, which is a steaming pile of warnings. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
* powerpc/amigaone: Add platform support for AmigaOneGerhard Pircher2009-02-11
| | | | | | | | | | | | | | | This commit adds the setup code for booting Linux on AmigaOne G3SE (G3 only), AmigaOne XE and uA1 (G3/G4) desktop computers. These boards were sold by Eyetech and are based on MAI Logic's Teron boards and its Articia S northbridge. The AmigaOne uses U-boot as firmware, which doesn't support a flattened device tree yet. The northbridge has some design flaws, which makes it necessary to use non cacheable memory for DMA operations (CONFIG_NOT_COHERENT_CACHE) and to avoid setting the coherence (M) flag for memory pages.

* [POWERPC] Fix interrupt routing and setup of ULI M1575 on FSL boardsKumar Gala2007-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The interrupt routing in the device trees for the ULI M1575 was inproperly using the interrupt line field as pci function. Fixed up the device tree's to actual conform for to specification and changed the interrupt mapping code so it just uses a static mapping setup as follows: PIRQA - IRQ9 PIRQB - IRQ10 PIRQC - IRQ11 PIRQD - IRQ12 USB 1.1 OCHI (1c.0) - IRQ12 USB 1.1 OCHI (1c.1) - IRQ9 USB 1.1 OCHI (1c.2) - IRQ10 USB 1.1 ECHI (1c.3) - IRQ11 LAN (1b.0) - IRQ6 AC97 (1d.0) - IRQ6 Modem (1d.1) - IRQ6 HD Audio (1d.2) - IRQ6 SATA (1f.1) - IRQ5 SMB (1e.1) - IRQ7 PMU (1e.2) - IRQ7 PATA (1f.0) - IRQ14/15 Took the oppurtunity to refactor the code into a single file so we don't have to duplicate these fixes on the two current boards in the tree and several forth coming boards that will also need the code. Fixed RTC support that requires a dummy memory read on the P2P bridge to unlock the RTC and setup the default of the RTC alarm registers to match with a basic x86 style CMOS RTC. Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure the PCI IO space has been setup properly before we start poking ISA registers at random locations.

* [POWERPC] Add powerpc/platforms/44x, disable platforms/4xx for nowDavid Gibson2007-05-08
| | | | | | | | | | | | | | | | | | | This prepares for Ebony/440 support by creating an arch/powerpc/platforms/44x directory. It is populated with a single misc_44x.S file, into which is moved the 44x specific reset code from head_44x.S (on the grounds that we should really stop clogging up the head_* files with random asm helper routines). At the same time, we disable the (empty save Kconfig and Makefile) arch/powerpc/platforms/4xx directory from the arch/powerpc/platforms Makefile. Contrary to the comment in arch/powerpc/platforms/4xx/Makefile, attempting to build such an empty Makefile will fail, thus breaking compile for the 44x platforms we're about to add. It can go back in once we start porting some of the 40x platforms (and thus it becomes non-empty).

* [POWERPC] Fix kernel build errors for mpc8272ads and mpc8560adsVitaly Bordug2007-02-06
| | | | | | | | | | | | | | | | | | | | Recent update of asm-powerpc/io.h caused cpm-related stuff to break in the current kernel. Current patch fixes it, as well as other inconsistencies expressed, that do not permit targets from working properly: - Updated dts with a chosen node with interrupt controller, - fixed messed device IDs among CPM2 SoC devices, - corrected odd header name and fixed type in defines, - Added 82xx subdir to the powerpc/platforms Makefile, missed during initial commit, - new solely-powerpc header file for 8260 family (was using one from arch/ppc, this one cleaned up from the extra stuff), in fact for now a placeholder to get the board-specific includes for stuff not yet capable to live with devicetree peeks only - Fixed couple of misprints in reference mpc8272 dts.
