* RealView: Add sparsemem support for the RealView PBX platformCatalin Marinas2009-11-054-3/+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>
* RealView: Remove duplicated #define REALVIEW_SYS_FLAGS* statementsColin Tuckley2009-11-051-4/+1

* RealView: Add default memory configurationCatalin Marinas2009-11-057-0/+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>
* ARM: 5774/1: Fix Realview ARM1176PB board rebootPhilby John2009-11-017-21/+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.

* ARM: 5720/1: Move MMCI header to amba include dirLinus Walleij2009-09-227-10/+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.

* ARM: 5718/1: Sane busids for RealView board componentsLinus Walleij2009-09-216-104/+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.

* [ARM] pass reboot command line to arch_reset()Russell King2009-03-191-1/+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.
