2009-12-09ARM: RealView: Fix typo in the RealView/PBX Kconfig entryCatalin Marinas1-1/+1
A previous patch was introducing a SPARSEMEM dependency on !HIGH_PHYS_OFFSET but it should actually be !REALVIEW_HIGH_PHYS_OFFSET. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2009-11-05RealView: Add sparsemem support for the RealView PBX platformCatalin Marinas4-3/+94
The RealView PBX board has two 512MB blocks of memory - one at 0x70000000 (with 256MB mirror at 0) and another at 0x20000000. Only the block at 0x70000000 (or the mirror at 0) may be used for DMA (e.g. framebuffer). This patch adds the sparsemem definitions to allow the use of all the memory split as follows: 256MB @ 0x00000000 (ZONE_DMA) 512MB @ 0x20000000 (ZONE_NORMAL) 256MB @ 0x80000000 (ZONE_NORMAL) Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2009-11-05RealView: Remove duplicated #define REALVIEW_SYS_FLAGS* statementsColin Tuckley1-4/+1
The platsmp.c file defines the REALVIEW_SYS_FLAGS* macros which are already present in platform.h. Just use the latter. Signed-off-by: Colin Tuckley <colin.tuckley@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2009-11-05RealView: Add default memory configurationCatalin Marinas7-0/+44
This patch adds a realview_fixup() function called during booting to set up the memory banks. This way there is no need to pass a "mem=" argument on the kernel command line. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2009-11-01ARM: 5774/1: Fix Realview ARM1176PB board rebootPhilby John7-21/+50
This is the fix for proper reboot of Realview ARM1176PB board when issuing the reboot command. Setting the eighth bit of control register SYS_RESETCTL to 1 to force a soft reset. arch_reset() is modified for realview machines to call machine specific reset function pointers.

2009-09-22ARM: 5720/1: Move MMCI header to amba include dirLinus Walleij7-10/+10
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.

2009-09-21ARM: 5718/1: Sane busids for RealView board componentsLinus Walleij6-104/+104
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. I kept the "dev:" prefix for DevChips, "fpga:" prefix for FPGA:s and "issp:" prefix for the other processor bus, just in case someone likes them.

2009-07-18ARM: Realview & Versatile: Fix i2c_board_info definitionsRussell King1-2/+1
Fix i2c_board_info definitions - we were defining the 'type' field of these structures twice since the first argument of I2C_BOARD_INFO sets this field.

2009-05-30RealView: Move the IRQ_* definitions out of the board-*.h filesCatalin Marinas12-461/+571

2009-05-30RealView: Toggle one LED per CPUCatalin Marinas1-3/+4
If CONFIG_LEDS is enabled, it makes more sense to toggle one LED per CPU in SMP systems rather than a single LED for all the CPUs. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2009-05-30RealView: Allow access to the secure flash memory block on PB1176Catalin Marinas3-5/+29

2009-05-17[ARM] realview: fix broadcast tick supportRussell King3-14/+6

2009-05-17[ARM] realview: remove useless smp_cross_call_done()Russell King2-14/+0
smp_cross_call_done() is a no-op for MPCore, and since it's only used by platform code, there's no point in having it unless it's doing something. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-05-17[ARM] smp: fix cpumask usage in ARM SMP codeRussell King2-5/+5

Set the "mult" to finite value in the local_timer_setup in case of CONFIG_LOCAL_TIMERS not enabled. Othewise this throws warning in the boot log because of detect zero event-device multiplicators.

2009-03-19[ARM] pass reboot command line to arch_reset()Russell King1-1/+1
OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.
