2011-03-26ARM: 6807/1: realview: Fix secondary GIC initialisation for EB with MPCore tilePawel Moll1-1/+1
The second GIC, present when EB board is used with a MPCore tile, was initialised starting with irq number 64, which made interrupts 64-95 in the primary GIC unusable. Signed-off-by: Pawel Moll <pawel.moll@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2011-02-19ARM: realview: remove old AMBA device DMA definitionsRussell King1-21/+0
The AMBA DMA macro definitions are not used, and the AMBA Primecell DMA support makes no use of them either, so they can be removed. Acked-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2011-02-18ARM: P2V: avoid initializers and assembly using PHYS_OFFSETRussell King1-1/+1
As PHYS_OFFSET will be becoming a variable, we can't have it used in initializers nor assembly code. Replace those in generic code with a run-time initialization. Replace those in platform code using the individual platform specific PLAT_PHYS_OFFSET.

2010-12-14ARM: GIC: consolidate gic_cpu_base_addr to common GIC codeRussell King1-4/+2
Every architecture using the GIC has a gic_cpu_base_addr pointer for GIC 0 for their entry assembly code to use to decode the cause of the current interrupt. Move this into the common GIC code.

2010-10-20arm: remove machine_desc.io_pg_offst and .phys_ioNicolas Pitre1-2/+0
Since we're now using addruart to establish the debug mapping, we can remove the io_pg_offst and phys_io members of struct machine_desc. The various declarations were removed using the following script: grep -rl MACHINE_START arch/arm | xargs \ sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }' [ Initial patch was from Jeremy Kerr, example script from Russell King ] Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Acked-by: Eric Miao <eric.miao at canonical.com>

This moves the mmci platform data definition struct away from arch/arm/include/asm/mach/mmc.h into the more proper place among the other primecells in include/linux/amba/mmci.h and at the same time renames it to "mmci.h", and also the struct in this file confusingly named mmc_platform_data has been renamed mmci_platform_data for clarity.

This removes the totally bogus bus ID:s with two-digit hex numerals either referring to the base address of corresponding versatile machine or just some arbitrarily chosen digit in favor of just using the device identifier as a string.

2008-12-01RealView: Use only the shadow mapping of ARM11MPCore local timersCatalin Marinas1-2/+1

2008-12-01RealView: Allow PHYS_OFFSET at 0x70000000Catalin Marinas1-1/+1
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>
2008-11-27[ARM] realview: convert to clkdev and lookup clocks by device nameRussell King1-2/+0
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>

2008-08-07[ARM] Remove asm/hardware.h, use asm/arch/hardware.h insteadRussell King1-1/+1
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>
2008-04-19Allow the L2X0 outer cache support to be configurableCatalin Marinas1-0/+2

2008-04-19RealView: Move more device address definitions to board-eb.hCatalin Marinas1-21/+21
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>
2008-04-19RealView: Move the UART definitions to EB specific filesCatalin Marinas1-16/+16
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>
2008-04-19RealView: Move the timer definitions into the EB specific filesCatalin Marinas1-4/+9
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>
2008-04-19RealView: Move the flash definitions out of platform.hCatalin Marinas1-1/+6

2008-02-04[ARM] 4821/1: RealView: Remove the platform dependencies from localtimer.cCatalin Marinas1-2/+6
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.

2008-02-04[ARM] 4820/1: RealView: Select the timer IRQ at run-timeCatalin Marinas1-1/+18
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 Marinas1-2/+4
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 Marinas1-41/+52

2008-02-04[ARM] 4817/1: RealView: Move the AMBA resource definitions to realview_eb.cCatalin Marinas1-1/+122
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.

2008-02-04[ARM] 4816/1: RealView: Move the platform-specific definitions into board-eb.hCatalin Marinas1-0/+1
This patch moves the platform specific definitions from platform.h into the board-eb.h file. It drops the INT_* definitions as they are no longer used in irqs.h (moved to board-eb.h). It renames REALVIEW_* macros to REALVIEW_EB_* or REALVIEW_EB11MP_* to distinguish between standard EB and EB + the ARM11MPCore tile. The platform.h file contains common definitions to the RealView platforms and it is only directly included in board-*.h files.

2007-02-15[ARM] 4109/2: Add support for the RealView/EB MPCore revC platformCatalin Marinas1-2/+2
The kernel originally supported revB only. This patch enables revC by default and adds a config option for building the kernel for the revB platform. Since the SCU base address was hard-coded in the proc-v6.S file (and only valid for RealView/EB revB), this patch also adds a more generic support for defining the SCU information.

2007-02-15[ARM] 4108/2: Allow multiple GIC interrupt controllers in a systemCatalin Marinas1-2/+2
