| * Make most arch asm/module.h files use asm-generic/module.hDavid Howells2012-09-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela, ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version into asm-generic/module.h for all arches bar MIPS. Also, use the generic definition mod_arch_specific where possible. To this end, I've defined three new config bools: (*) HAVE_MOD_ARCH_SPECIFIC Arches define this if they don't want to use the empty generic mod_arch_specific struct. (*) MODULES_USE_ELF_RELA Arches define this if their modules can contain RELA records. This causes the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be defined by the arch rather than have the core emit an error message. (*) MODULES_USE_ELF_REL Arches define this if their modules can contain REL records. This causes the Elf_Rel mapping to be emitted and allows apply_relocate() to be defined by the arch rather than have the core emit an error message. Note that it is possible to allow both REL and RELA records: m68k and mips are two arches that do this. With this, some arch asm/module.h files can be deleted entirely and replaced with a generic-y marker in the arch Kbuild file. Additionally, I have removed the bits from m32r and score that handle the unsupported type of relocation record as that's now handled centrally.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The microblaze architecture does not provide a native GPIO API implementation nor requires GPIOLIB, but still selects GENERIC_GPIO by default. As a result the following build error occurs, if GPIOLIB is not selected: include/asm-generic/gpio.h: In function 'gpio_get_value_cansleep': include/asm-generic/gpio.h:218: error: implicit declaration of function '__gpio_get_value' include/asm-generic/gpio.h: In function 'gpio_set_value_cansleep': include/asm-generic/gpio.h:224: error: implicit declaration of function '__gpio_set_value' This patch addresses the issue by not selecting GENERIC_GPIO by default.

* | timers: Fixup the Kconfig consolidation falloutThomas Gleixner2012-05-211-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sigh, I missed to check which architecture Kconfig files actually include the core Kconfig file. There are a few which did not. So we broke them. Instead of adding the includes to those, we are better off to move the include to init/Kconfig like we did already with irqs and others. This does not change anything for the architectures using the old style periodic timer mode. It just solves the build wreckage there. For those architectures which use the clock events infrastructure it moves the include of the core Kconfig file to "General setup" which is a way more logical place than having it at random locations specified by the architecture specific Kconfigs.

* microblaze: switch to GENERIC_PCI_IOMAPMichael S. Tsirkin2011-11-281-0/+1
| | | | | | | | | | | | | microblaze copied pci_iomap from generic code, probably to avoid pulling the rest of iomap.c in. Since that's in a separate file now, we can reuse the common implementation. The only difference is handling of nocache flag, that turns out to be done correctly by the generic code since arch/microblaze/include/asm/io.h defines ioremap_nocache same as ioremap.

| | | | | | | | | | | | | | | | | The device tree code is now in two pieces: some which can be used generically on any platform which selects CONFIG_OF_FLATTREE, and some early which is used at boot time on only a few architectures. This patch segregates the early code so that only those architectures which care about it need compile it. This also means that some of the requirements in the early code (such as a cmd_line variable) that most architectures (e.g. X86) don't provide can be ignored.

Putting all of them inside a menu block simplifies the dependency statements. It also creates a logical group for adding user selectable OF options. This patch also changes (PPC_OF || MICROBLAZE) statements to (!SPARC) so that those options are available to other architectures (and in fact the !SPARC conditions should probably be re-evalutated since the code is more generic now) This patch also moves the definition of CONFIG_DTC from arch/* to drivers/of/Kconfig Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

User space calling is not supported because user application debugging uses different handling. pt_regs_to_gdb_regs loads additional special registers which can't be changed * Enable KGDB in Kconfig * Remove ancient not-tested KGDB support * Remove ancient _debug_exception code from entry.S Only MMU KGDB support is supported.

* microblaze: Add consistent codeMichal Simek2010-03-111-0/+9
| | | | | | | | | | | | | | | Remove ancient Kconfig option for consistent code. MMU uses cache inhibit pages. noMMU uses UNCACHE SHADOW feature where is used double ram size. For example: Physical ram is 256MB and cache are setup to cover the same size. But if you setup in HW that size is 512MB and cache covers 256MB than you can use adresses from 256-512MB without caches and correspond with 0-256MB with cache. That's why I am using dcache base/high addresses to find out uncache area. Signed-off-by: Michal Simek <monstr@monstr.eu>

* microblaze: Add support for Xilinx PCI host bridgeMichal Simek2010-03-111-0/+4
| | | | | | | | | | | | | | This patch is based on powerpc patch 64f16502475ddf663169369fffff6da9b10ea9fb We did some cleanups and removed powerpc parts. There is one new debug early listing function too. Exclude function is only in Debug options. We tested in on custom board. Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Enable PCI, missing filesMichal Simek2010-03-111-0/+15
| | | | | | | | | | | | | | There are two parts of changes. The first is just enable PCI in Makefiles and in Kconfig. The second is the rest of missing files. I didn't want to add it with previous patch because that patch is too big. Current Microblaze toolchain has problem with weak symbols that's why is necessary to apply this changes to be possible to compile pci support. Xilinx knows about this problem.

* microblaze: Support DMAMichal Simek2010-03-111-3/+2
| | | | | | | | | | | | | | | | | | Add DMA support for Microblaze. There are some part of this new feature: 1. Basic DMA support 2. Enable DMA debug option 3. Setup notifier Ad 1. dma-mapping come from powerpc and x86 version and it is based on generic dma-mapping-common.h Ad 2. DMA support debug features which is used in generic file. For more information please look at Documentation/DMA-API.txt Ad 3. notifier is very important to setup dma_ops. Without this part for example ll_temac driver failed because there are no setup dma operations. Signed-off-by: Michal Simek <monstr@monstr.eu>
