2008-12-01RealView: Select CPU_V6 for MACH_REALVIEW_PB11MPCatalin Marinas
This seems to be missing from the arm:devel branch, though the other RealView configurations were modified accordingly. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-12-01RealView: Allow the in-kernel smc911x.c driver on RealViewCatalin Marinas
This patch adds smc911x.c device configuration to the RealView platforms. At some point it may be changed to the new smsc911x.c driver (once complete testing was done). Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-12-01RealView: Refactor the Ethernet device registrationCatalin Marinas
This patch moves the Ethernet device registration from individual realview_*.c files to core.c. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-12-01RealView: Clean up the machine_is_*() calls in platsmp.cCatalin Marinas
Some of the calls weren't necessary and some others were duplicated. This patch tidies up the platsmp.c file. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-12-01RealView: Use only the shadow mapping of ARM11MPCore local timersCatalin Marinas
All the cases where the local timer for a CPU is accessed happen on the corresponding current CPU, hence no need to access the per-CPU local timer mappings. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-12-01RealView: Add Cortex-A9 support to the EB boardJon Callan
This patch adds the necessary definitions and Kconfig entries to enable Cortex-A9 (ARMv7 SMP) tiles on the RealView/EB board. Signed-off-by: Jon Callan <Jon.Callan@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-12-01RealView: Use flush_cache_all() rather than MCR in cpu_enter_lowpower()Harry Fearnhamm
The MCR for flushing the whole D cache is undefined on ARMv7 CPUs. Signed-off-by: Harry Fearnhamm <Harry.Fearnhamm@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-12-01RealView: Add support for the Cortex-A8 Platform BaseboardBahadir Balban
This patch adds support for RealView/PB-A8, a platform based on Cortex-A8 with support for PCI-E and compact flash. Signed-off-by: Bahadir Balban <bahadir.balban@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-12-01RealView: Allow PHYS_OFFSET at 0x70000000Catalin Marinas
RealView boards like PB11MPCore have 512MB of RAM available contiguously at 0x70000000. Half of the memory is mirrored at 0x00000000 for backwards compatibility. This patch adds the CONFIG_REALVIEW_HIGH_PHYS_OFFSET option option to change the physical base address so that the full amount of RAM is available to Linux. Note that the EB board has 256MB of RAM also mirrored at 0x70000000, the only board without this feature being PB1176. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-11-30[ARM] Add a common typesafe __io implementationRussell King
As Al did for Versatile in 2ad4f86b60b649fd7428265c08d73a3bd360c81b, add a typesafe __io implementation for platforms to use. Convert platforms to use this new simple typesafe implementation. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-29[ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King
When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-28Merge branch 'highmem' into develRussell King
Conflicts: arch/arm/mach-clps7500/include/mach/memory.h
2008-11-28[ARM] remove a common set of __virt_to_bus definitionsNicolas Pitre
Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.

2008-11-27[ARM] realview: convert to clkdev and lookup clocks by device nameRussell King
People often point to the Integrator/Versatile/Realview implementations to justify using the consumer name as the sole selector for clocks. Eliminate this excuse by changing the Realview implementation, so it provides a better example of how it should be done. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-27[ARM] Arrange for platforms to select appropriate CPU supportRussell King
Rather than: config CPU_BLAH bool depends on ARCH_FOO || MACH_BAR default y if ARCH_FOO || MACH_BAR arrange for ARCH_FOO and MACH_BAR to select CPU_BLAH directly. Acked-by: Nicolas Pitre <nico@marvell.com> Acked-by: Andrew Victor <linux@maxim.org.za> Acked-by: Brian Swetland <swetland@google.com> Acked-by: Eric Miao <eric.miao@marvell.com> Acked-by: Nicolas Bellido <ml@acolin.be> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-13[ARM] integrator,realview,versatile: remove FLASH_* and EPROM_* constantsRussell King
FLASH_* and EPROM_* constants are unused, and clash with drivers: drivers/atm/ambassador.h:257:1: warning: "FLASH_BASE" redefined drivers/atm/ambassador.h:258:1: warning: "FLASH_SIZE" redefined drivers/atm/iphase.h:332:1: warning: "EPROM_SIZE" redefined so remove them. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-10RealView: Make more vmalloc space by changing IO_ADDRESSCatalin Marinas
Since boards like PB11MPCore have 512MB of RAM and 128MB of flash, the virtual space is short on vmalloc memory and mapping the flash fails. This patch changes the IO_ADDRESS so that static mappings start at 0xfc000000 and moves the PCI virtual addresses higher up. The new VMALLOC_END is set to 0xf8000000 (512MB higher than the old value). Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-11-10RealView: Add debug-macro.S support for the PB1176 platformCatalin Marinas
The UART0 address is different on PB1176 from EB or PB11MPCore. This patch adds the necessary #ifdef's to this file. The disadvantage is that enabling CONFIG_DEBUG_LL will work properly on PB1176 if only this platform is enabled. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-11-10RealView: Change the clcd panel controls to use RGB instead of BGRCatalin Marinas
Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-11-10RealView: Allow XVGA (1024x768) CLCD resolution on the RealView boardsColin Tuckley
This patch adds another clcd_panel structure for the above resolution and makes it the default for the PB1176 and PB11MPCore platforms. Signed-off-by: Colin Tuckley <Colin.Tuckley@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-11-10RealView: Use the correct oscillator for the CLCD on PB1176Colin Tuckley
On PB1176, oscillator 0 rather than 4 should be used. Signed-off-by: Colin Tuckley <colin.tuckley@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-11-08[ARM] realview: correct MMC clock rateRussell King
The MMC clock source is actually 24MHz, not 33MHz. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-09-06[ARM] Convert asm/io.h to linux/io.hRussell King
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-08-07[ARM] Move include/asm-arm/arch-* to arch/arm/*/include/machRussell King
This just leaves include/asm-arm/plat-* to deal with. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-08-07[ARM] Remove asm/hardware.h, use asm/arch/hardware.h insteadRussell King
Remove includes of asm/hardware.h in addition to asm/arch/hardware.h. Then, since asm/hardware.h only exists to include asm/arch/hardware.h, update everything to directly include asm/arch/hardware.h and remove asm/hardware.h. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-06-30[ARM] 5131/1: Annotate platform_secondary_init with trace_hardirqs_offCatalin Marinas
This patch annotates the platform_secondary_init function in arch/arm/mach-realview/platsmp.c with trace_hardirqs_off to avoid a warning when LOCKDEP and TRACE_IRQFLAGS are enabled. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-04-18arch: Remove unnecessary inclusions of asm/semaphore.hMatthew Wilcox
None of these files use any of the functionality promised by asm/semaphore.h. It's possible that they rely on it dragging in some unrelated header file, but I can't build all these files, so we'll have fix any build failures as they come up. Signed-off-by: Matthew Wilcox <willy@linux.intel.com>
2008-04-18Allow the L2X0 outer cache support to be configurableCatalin Marinas
By default, this option was selected by the platform Kconfig. This patch adds "depends on" to L2X0 so that it can be enabled/disabled manually. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

2008-04-18RealView: Move more device address definitions to board-eb.hCatalin Marinas
The upcoming PB11MPCore and PB1176 have different memory maps and some of the definitions in platform.h are no longer common. This patch moves them to the board-eb.h file and updates their usage in realview_eb.c. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-04-18RealView: Move the UART definitions to EB specific filesCatalin Marinas
Since the PB1176 has different UART base addresses, this patch moves the definitions form platorm.h to board-eb.h. It also modifies uncompress.h to detect the platform type at run-time. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-04-18RealView: Move the timer definitions into the EB specific filesCatalin Marinas
This patch moves the timer definitions from platform.h into board-eb.h as they are different on PB11MPCore and PB1176. It also adds timerX_va_base variables in core.c which are set by the realview_eb_timer_init function before invoking realview_timer_init. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-04-18RealView: Move the flash definitions out of platform.hCatalin Marinas
This patch moves the patch definitions into board-eb.h and realview_eb.c (from core.c) as they are different on the PB11MPCore and PB1176 platforms. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-04-18RealView: Move the EB GIC definitions to the board fileCatalin Marinas
This is in preparation for the RealView PB11MPCore and PB1176 patches which have different base addresses for the GIC. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-04-18Add RealView/EB support for the LAN9118 Ethernet chipCatalin Marinas
RealView/EB revD platform comes with the SMSC LAN9118 Ethernet chip. This patch allows either the smc91x or the smc911x drivers to be used with the RealView/EB platform. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-04-18RealView: Move the SCU initialisation out of __v6_setupCatalin Marinas
This patch moves the SCU initialisation from __v6_setup to the smp_prepare_cpus() function as it relies on platform-specific settings. Changes to get_core_count() are mainly for allowing cleaner code with the upcoming PB11MPCore patches. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-02-04[ARM] 4822/1: RealView: Change the REALVIEW_MPCORE configuration optionCatalin Marinas
This patch changes the REALVIEW_MPCORE configuration option to REALVIEW_EB_ARM11MP since this is only specific to RealView/EB. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4821/1: RealView: Remove the platform dependencies from localtimer.cCatalin Marinas
This patch removes the TWD_BASE macro used to set up and configure the local timers on ARM11MPCore. The twd_base_addr and twd_size variables are defined in localtimer.c and set from the realview_eb_init function. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4820/1: RealView: Select the timer IRQ at run-timeCatalin Marinas
This patch sets the timer IRQ at run-time by moving the sys_timer structure and the timer_init function to the realview_eb.c file. This allows multiple RealView platforms to be compiled in the same kernel image. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4819/1: RealView: Fix entry-macro.S to work with multiple platformsCatalin Marinas
This patch modifies the get_irqnr_preamble macro to work with multiple platforms at run-time by reading the address of the GIC controller from the gic_cpu_base_addr variable. This variable is defined in core.c and intialised in realview_eb.c (gic_init_irq). Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4818/1: RealView: Add core-tile detectionCatalin Marinas
This patch adds the core-tile detection and only enables devices if the corresponding tile is present. It currently detects the ARM11MPCore via the core_tile_eb11mp() macro. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4817/1: RealView: Move the AMBA resource definitions to realview_eb.cCatalin Marinas
This patch moves the IRQ and DMA definitions from core.h into realview_eb.c since they are platform-specific. It adds a realview_eb11mp_fixup function to adjust the IRQ numbers if the ARM11MPCore tile is fitted. The realview_smc91x_device is also moved from core.c into realview_eb.c.
