2007-02-09[TC] TURBOchannel support for the DECstationMaciej W. Rozycki
This is the platform-specific part of TURBOchannel bus support for the DECstation. It implements determining whether the bus is actually there, getting bus parameters, IRQ assignments for devices and protected accesses to possibly unoccupied slots that may trigger bus error exceptions.

2007-02-09[AVR32] SPI platform code updateHaavard Skinnemoen
Move stuff in spi.c into ATSTK1002 board code and update SPI platform device definitions according to the new GPIO API. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-02-09[AVR32] Add PIOE device and reserve SDRAM pinsHaavard Skinnemoen
The PIOE device was left out before because it muxes SDRAM pins (and is therefore a bit dangerous to mess with) and because no existing drivers had any use for it. It is needed for CompactFlash, however, and now that we have a way to protect the SDRAM pins, it can be safely added. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-02-09[AVR32] Introduce at32_reserve_pin()Haavard Skinnemoen
at32_reserve_pin() can be used for reserving portmux pins without altering their configuration. Useful for e.g. SDRAM pins where we really don't want to change the bootloader-provided configuration. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-02-09[AVR32] Don't reset PIO state at bootupHaavard Skinnemoen

2007-02-09[AVR32] Fix incorrect invalidation of shared cachelinesDavid Brownell
Fix bug in dma_map_single(..., DMA_FROM_DEVICE) caused by incorrect invalidation of shared cachelines at the beginning and/or end of the specified buffer. Those shared cachelines need to be flushed, since they may hold valid data (which must not be discarded).

2007-02-09[AVR32] ext int fixesDavid Brownell
Bugfixes for external irq handler set_irq_type(): - If set_irq_type() can't set the type, don't change anything! - It's not OK to change the flow handler as part of set_irq_type(), among other issues that violates spinlock rules. Instead, we can call the relevant handler when we demux the external interrupts. - The external irq demux has no need to grab the spinlock. And in fact grabbing it that way was wrong, since that code might be pre-empted by an irq at a different priority level, and that code might then have tried to grab that spinlock...

Rename the 'us_regs' field of the ucc_slow_info structure in ucc_slow.h to just 'regs'. The equivalent field in the ucc_fast_info structure is also called 'regs', so this patch makes them comparable, and makes the code a little easier to read, because there already is a 'us_regs' in another ucc_slow structure.

2007-02-08[ARM] 4154/1: AT91: Clock updateAndrew Victor
Unconditionally disabling the PCKs (Programmable Clocks) is not a good idea as it breaks boards that depend on those clocks being enabled by bootloaders. Therefore only disable unused clocks late in the init process, giving the board init code the chance to claim the clock. Patch from Steven Scholz. Since the HCK clocks on SAM9261 are already being registered as a independent clocks, we don't need the special case for HCK0 on the SAM9261. Platform-init code and drivers should use the clock API to enable/disable the clock. Patch from Nicolas Ferre.

2007-02-08[ARM] Always mark ARMv6 PTWs outer cacheableRussell King
Other platforms other than SMP may have an outer cache. For these, we also need to mark the page table walks outer cacheable. Since marking the walks always outer cacheable apparantly has no side effects, we might as well always mark them so. However, we continue to only mark PTWs shared if we have SMP enabled.

2007-02-08[ARM] 4143/1: AT91: Prepare for AT91SAM9263 supportAndrew Victor
The Atmel AT91SAM9263 processor includes many more integrated peripherals than Atmel's previous ARM9-based AT91 processors, so this has necessitated a few changes to the core AT91 support. These changes are: * The system peripheral I/O region we remap has increased from 0xFFFA0000..0xFFFFFFFF to 0xFFF78000..0xFFFFFFFF. * The increased I/O region forces changes to entry-macro.S and debug-macro.S due to ARM's limited immediate offset addressing modes. * Maximum number of GPIO banks increases to 5. * 2 MMC controllers so the board-setup code needs to specify which controller it wishes to use when calling at91_add_device_mmc().

2007-02-08[ARM] 4124/1: Rename mach-at91rm9200 and arch-at91rm9200 directoriesAndrew Victor
Now that Linux includes support for the Atmel AT91SAM9260 and AT91SAM9261 processors in addition to the original Atmel AT91RM9200 (with support for more AT91 processors pending), the "mach-at91rm9200" and "arch-at91rm9200" directories should be renamed to indicate their more generic nature. The following git commands should be run BEFORE applying this patch: git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91 git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91 Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-02-08[ARM] 4119/1: AT91: Fix build of AT91SAM9260Andrew Victor
Fix build failure of AT91SAM9260. The AT91RM9200 ethernet driver (at91_ether.c) stores platform data in a "struct at91_eth_data" structure, but the AT91SAM9260 (and AT91SAM9263) ethernet driver (macb.c) [developed on the AVR32 architecture] expects a "struct eth_platform_data". Since the platform data of the two drivers is very similar, we continue to use the "struct at91_eth_data" for all AT91 processors but add a #define eth_platform_data at91_eth_data in board.h to keep the MACB driver happy.

2007-02-08[ARM] Convert DMA cache handling to take const void * argsRussell King
The DMA cache handling functions take virtual addresses, but in the form of unsigned long arguments. This leads to a little confusion about what exactly they take. So, convert them to take const void * instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-02-08[ARM] 4134/1: Add generic support for outer cachesCatalin Marinas
The outer cache can be L2 as on RealView/EB MPCore platform or even L3 or further on ARMv7 cores. This patch adds the generic support for flushing the outer cache in the DMA operations.

2007-02-08[ARM] Don't call consistent_sync() for DMA coherent memoryRussell King
Memory allocated by the coherent memory allocators will be marked uncacheable, which means it's pointless calling consistent_sync() to perform cache maintainence on this memory; it's just a waste of CPU cycles. Moreover, with the (subsequent) merge of outer cache support, it actually breaks things to call consistent_sync() on anything but direct-mapped memory. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-02-08[ARM] 4129/1: Add barriers after the TLB operationsCatalin Marinas
The architecture specification states that TLB operations are guaranteed to be complete only after the execution of a DSB (Data Synchronisation Barrier, former Data Write Barrier or Drain Write Buffer). The branch target cache invalidation is also needed. The ISB (Instruction Synchronisation Barrier, formerly Prefetch Flush) is needed unless there will be a return from exception before the corresponding mapping is used (i.e. user mappings).

2007-02-08[ARM] 4128/1: Architecture compliant TTBR changing sequenceCatalin Marinas
On newer architectures (ARMv6, ARMv7), the depth of the prefetch and branch prediction is implementation defined and there is a small risk of wrong ASID tagging when changing TTBR0 before setting the new context id. The recommended solution is to set a reserved ASID during TTBR changing. This patch reserves ASID 0.

2007-02-08[ARM] 4123/1: xsc3: general cleanupLennert Buytenhek
This patch cleans up proc-xsc3: - Correct a number of typos. - Fix up indentation in a number of places. - Change references to the various caches to be more clear about whether we're talking about the L1 D, the L1 I or the unified L2 cache. - Rename "drain write buffer" to "data write barrier", the official name used in the Manzano manual. - Change the xsc3 cpu name from "XScale-Core3" to "XScale-V3 based processor". Also, since a previously merged patch implements proper support for using a MAC or iWMMXt coprocessor on xsc3 platforms, we no longer need to enable access to CP0 on boot.
