* MIPS: Lantiq: Add PCI controller support.John Crispin2011-05-194-0/+432
| | | | | | | | | | | | | | | | The Lantiq family of SoCs have a EBU (External Bus Unit). This patch adds the driver that allows us to use the EBU as a PCI controller. In order for PCI to work the EBU is set to endianess swap all the data. In addition we need to make use of SWAP_IO_SPACE for device->host DMA to work. The clock of the PCI works in several modes (internal/external). If this is not configured correctly the SoC will hang.

| | | | | | | | | | | | | All Octeon chips can support more than 4GB of RAM. Also due to how Octeon PCI is setup, even some configurations with less than 4GB of RAM will have portions that are not accessible from 32-bit devices.

* MIPS: Octeon: Allow more than 3.75GB of memory with PCIeDavid Daney2010-08-051-6/+31
| | | | | | | | | | | | | | | | | We reserve the 3.75GB - 4GB region of PCIe address space for device to device transfers, making the corresponding physical memory under direct mapping unavailable for DMA. To allow for PCIe DMA to all physical memory we map this chunk of physical memory with BAR1. Because of the resulting discontinuity in the mapping function, we remove a page of memory at each end of the range so multi-page DMA buffers can never be allocated that span the range.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* MIPS: Cobalt: convert legacy port addresses to GT-64111 bus addressesBjorn Helgaas2010-02-272-2/+61
| | | | | | | | | | | | | | | | | | | | | | | | The GT-64111 PCI host bridge has no address translation mechanism, so it can't generate legacy port accesses. This quirk fixes legacy device port resources to contain the bus addresses actually generated by the GT-64111. I think this is the approach Ben Herrenschmidt suggested long ago: http://marc.info/?l=linux-kernel&m=119733290624544&w=2 This allows us to remove the IORESOURCE_PCI_FIXED hack from pcibios_fixup_device_resources(), which converts bus addresses to CPU addresses. IORESOURCE_PCI_FIXED denotes resources that can't be moved; it has nothing to do with converting bus to CPU addresses.

* MIPS: Loongson: Change naming methodsWu Zhangjin2009-09-173-3/+3
| | | | | | | | | | | | To make source code of loongson sharable to the machines(such as gdium) made by the other companies, we rename arch/mips/lemote to arch/mips/loongson, asm/mach-lemote to asm/mach-loongson, and rename lm2e to the name of the machine: fuloong-2e. accordingly, FULONG are renamed to FULOONG2E to make it distinguishable to the future FULOONG2F. and also, some other relative tuning is needed.

* MIPS: Loongson: clean up the coding styleWu Zhangjin2009-09-171-18/+0
| | | | | | | | | | | | | | | | | | With the help of script/checkpatch.pl, i have cleaned up the coding style. 1. remove un-needed header files and tune some comments. 2. remove some un-needed { } add a new header file loongson.h: 3. move some common header files to loongson.h 4. move some common extern declartions to loongson.h and this new header file is needed for future loongson2f support.

| | | | | | | | | Some of the were relying into smp.h being dragged in by another header which of course is fragile. <asm/cpu-info.h> uses smp_processor_id() only in macros and including smp.h there leads to an include loop, so don't change cpu-info.h.

* PCI: mips: use generic INTx swizzle from PCI coreBjorn Helgaas2009-01-071-16/+1
| | | | | | | | | | | Use the generic pci_common_swizzle() instead of arch-specific code. Note that pci_common_swizzle() loops based on dev->bus->self, not dev->bus->parent as the mips common_swizzle() did. I think they are equivalent for this purpose.
