That function isn't trivial, and we are going to modify it https://lkml.org/lkml/2011/11/14/183 so the duplication hurts. This reduces the scope of the problem significantly, by moving pci_iomap to a separate file and referencing that from all architectures. * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost: alpha: drop pci_iomap/pci_iounmap from pci-noop.c mn10300: switch to GENERIC_PCI_IOMAP mn10300: add missing __iomap markers frv: switch to GENERIC_PCI_IOMAP tile: switch to GENERIC_PCI_IOMAP tile: don't panic on iomap sparc: switch to GENERIC_PCI_IOMAP sh: switch to GENERIC_PCI_IOMAP powerpc: switch to GENERIC_PCI_IOMAP parisc: switch to GENERIC_PCI_IOMAP mips: switch to GENERIC_PCI_IOMAP microblaze: switch to GENERIC_PCI_IOMAP arm: switch to GENERIC_PCI_IOMAP alpha: switch to GENERIC_PCI_IOMAP lib: add GENERIC_PCI_IOMAP lib: move GENERIC_IOMAP to lib/Kconfig Fix up trivial conflicts due to changes nearby in arch/{m68k,score}/Kconfig

| | | | | | | | | | | | | | | | | | | | | | The pci_iomap variant that arch/mn10300/unit-asb2305/pci-iomap.c uses differs from the generic one in that it does not use ioremap_nocache for PCI addresses. However, it turns out that PCI addresses are automatically noncached, so switching to ioremap_nocache and to the generic implementation is safe. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some SoCs have a timer block enable controlled through the DSCR registers. There is a problem in the timer64 driver initialization where the code accesses a timer register to get the divisor used to calculate timer clock rate. If the timer block has not been enabled when this register read takes place, an exception is generated. This patch makes sure that the timer block is enabled before accessing the registers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All SoCs provide an area of device configuration registers called the DSCR. The location of specific registers as well as their use varies considerably from implementation to implementation. Rather than having to rely on additional SoC-specific DSCR code for each new supported SoC, this code generalize things as much as possible using device tree properties. Initialization must take place early on (setup_arch time) in case the event timer device needs to be enable via the DSCR.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several SoC parts provide a simple bridge to support external memory mapped devices. This code probes the device tree for an EMIF node and sets up the bridge registers if such a node is found. Beyond initial set up, there is no further need to access the bridge control registers. External devices on the bus are accessed through their MMIO registers using suitable drivers. The bridge hardware does provide for timeout and other error interrupts, but these are not yet supported.

Brought up to date by Mark Salter <msalter@redhat.com> The C6X architecture currently lacks an MMU so memory management is relatively simple. There is no bus snooping between L2 and main memory but coherent DMA memory is supported by making regions of main memory uncached. If such a region is desired, it can be specified on the commandline with a "memdma=" argument.

| * | C6X: devicetree supportMark Salter2011-10-0617-0/+1087

Currently, four boards are supported. Each one uses a different SoC part. Two of the four supported SoCs are multicore. One with 3 cores and the other with 6 cores. There is no coherency between the core-level caches, so SMP is not an option. It is possible to run separate kernel instances on the various cores. There is currently no C6X bootloader support for device trees so we build in the DTB for now. There are some interesting twists to the hardware which are of note for device tree support. Each core has its own interrupt controller which is controlled by special purpose core registers. This core controller provides 12 general purpose prioritized interrupt sources. Each core is contained within a hardware "module" which provides L1 and L2 caches, power control, and another interrupt controller which cascades into the core interrupt controller. These core module functions are controlled by memory mapped registers. The addresses for these registers are the same for each core. That is, when coreN accesses a module-level MMIO register at a given address, it accesses the register for coreN even though other cores would use the same address to access the register in the module containing those cores. Other hardware modules (timers, enet, etc) which are memory mapped can be accessed by all cores. The timers need some further explanation for multicore SoCs. Even though all timer control registers are visible to all cores, interrupt routing or other considerations may make a given timer more suitable for use by a core than some other timer. Because of this and the desire to have the same image run on more than one core, the timer nodes have a "ti,core-mask" property which is used by the driver to scan for a suitable timer to use.

Brought up to date by Mark Salter <msalter@redhat.com> This patch provides the early boot code for C6X architecture. There is a 16 entry vector table which is used to direct reset and interrupt events. The vector table entries contain a small amount of code (maximum of 8 opcodes) which simply branches to the actual event handling code. The head.S code simply clears BSS, setups up a few control registers, and calls machine_init followed by start_kernel. The machine_init code in setup.c does the early flat tree parsing (memory, commandline, etc). At setup_arch time, the code does the usual memory setup and minimally scans the devicetree for any needed information.

| | | | | | | | | | | | | | | | | | | | | | | | | | | asm-generic/page.h had several problems when used with a non-zero PAGE_OFFSET. This patch adds a default ARCH_PFN_OFFSET and fixes the __va, __pa, and pfn_valid macros to work with non-zero PAGE_OFFSETs.
