| * ARM: OMAP: Remove NEED_MACH_GPIO_HTony Lindgren2012-11-021-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Omap no longer needs this option, mach/gpio.h is empty. Also remove mach/irqs.h from gpio-omap.h and include it directly from the related omap1 gpio init files. Otherwise omap2+ build fails for MULTI_PLATFORM.

* | ARM: pxa: remove pxa95x supportHaojian Zhuang2012-11-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | PXA95x isn't widely used. And it adds the effort on supporting multiple platform. So remove it. The assumption is that nobody will miss this support. If you are reading this text because you actually require pxa95x support on a new kernel, we can work out a way to revert this patch or add support to the mmp platform.

Remove what is upstream for now, until the out-of-tree implementation is in suitable form for merging. An important side effect of this patch is that it allows the building of a Zynq kernel without running into unresolved symbol problems: drivers/built-in.o: In function `amba_get_enable_pclk': clkdev.c:(.text+0x444): undefined reference to `clk_enable' drivers/built-in.o: In function `amba_remove': clkdev.c:(.text+0x488): undefined reference to `clk_disable' drivers/built-in.o: In function `amba_probe': clkdev.c:(.text+0x540): undefined reference to `clk_disable' drivers/built-in.o: In function `amba_device_add': clkdev.c:(.text+0x77c): undefined reference to `clk_disable' drivers/built-in.o: In function `enable_clock': clkdev.c:(.text+0x29738): undefined reference to `clk_enable' drivers/built-in.o: In function `disable_clock': clkdev.c:(.text+0x29778): undefined reference to `clk_disable' drivers/built-in.o: In function `__pm_clk_remove': clkdev.c:(.text+0x297f8): undefined reference to `clk_disable' drivers/built-in.o: In function `pm_clk_suspend': clkdev.c:(.text+0x29bc8): undefined reference to `clk_disable' drivers/built-in.o: In function `pm_clk_resume': clkdev.c:(.text+0x29c28): undefined reference to `clk_enable' make[2]: *** [vmlinux] Error 1 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2 In addition, eliminate Zynq's "use" of the versatile platform, as it is no longer needed. As Nick Bowler points out: For the record, I think this was introduced by commit 56a34b03ff427 ("ARM: versatile: Make plat-versatile clock optional") which forgot to select PLAT_VERSATILE_CLOCK on Zynq. This is not all that surprising, because the fact that Zynq "uses" PLAT_VERSATILE is secretly hidden in the Makefile. Nevertheless, the only feature from versatile that Zynq needed was the clock support, so this patch should *also* delete the secret use of plat-versatile by removing this line from arch/arm/Makefile: plat-$(CONFIG_ARCH_ZYNQ) += versatile Signed-off-by: Josh Cartwright <josh.cartwright@ni.com> Cc: John Linn <john.linn@xilinx.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Tested-by: Michal Simek <michal.simek@xilinx.com>

| * | Make most arch asm/module.h files use asm-generic/module.hDavid Howells2012-09-281-0/+2

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.

However, the Armada 370 and XP SoCs will not use the MPP and GPIO code (instead some proper pinctrl and gpio drivers are in preparation), and generally, we want to move away from plat-orion and instead have everything in mach-mvebu. That said, in the mean time, we want to leverage the driver-specific headers as well as the address decoding code, so we introduce PLAT_ORION_LEGACY. The older Marvell SoCs need to select PLAT_ORION_LEGACY, while the newer Marvell SoCs need to select PLAT_ORION. Of course, when PLAT_ORION_LEGACY is selected, it automatically selects PLAT_ORION. Then, with just PLAT_ORION, you have the address decoding code plus the driver-specific headers. If you add PLAT_ORION_LEGACY to this, you gain the old MPP, GPIO and PCIe code. Again, this is only a temporary solution until we make all Marvell EBU platforms converge into the mach-mvebu directory. This solution avoids duplicating the existing address decoding code into mach-mvebu.

PV console, block and network frontend/backends are working. Bug-fixes: * Fix compile linux-next fallout. * Fix PVHVM bootup crashing. The Xen-unstable hypervisor (so will be 4.3 in a ~6 months), supports ARMv7 platforms. The goal in implementing this architecture is to exploit the hardware as much as possible. That means use as little as possible of PV operations (so no PV MMU) - and use existing PV drivers for I/Os (network, block, console, etc). This is similar to how PVHVM guests operate in X86 platform nowadays - except that on ARM there is no need for QEMU. The end result is that we share a lot of the generic Xen drivers and infrastructure.

It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while. Sorry for the overhead."

However, it will not be useful for any real work, because it relies on a number of useful things to be disabled for now: * SMP support must be turned off because of conflicting symbols. Marc Zyngier has proposed a solution by adding a new SOC operations structure to hold indirect function pointers for these, but that work is currently stalled * We turn on SPARSE_IRQ unconditionally, which is not supported on most platforms. Each of them is currently in a different state, but most are being worked on. * A common clock framework is in place since v3.4 but not yet being used. Work on this is on its way. * DEBUG_LL for early debugging is currently disabled. * THUMB2_KERNEL does not work with allyesconfig because the kernel gets too big [Rob Herring]: Rebased to not be dependent on the mass mach header rename. As a result, omap2plus, imx, mxs and ux500 are not converted. Highbank, picoxcell, mvebu, and socfpga are converted.
