* ARM: v6k: Realview EB 11MPCore and PB11MPCore use V6K architecture CPUsRussell King2011-02-02
| | | | | | | | Make Realview EB ARM11MPCore and PB11MPCore select the new V6K CPU option. Tested-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: realview: name configuration options after actual board namesRussell King2011-01-25
| | | | | | | | | | | | | | | | | | | | As no one seems to really know which configuration options tie up with which boards, I thought I'd do some investigation and try to work it out. After discussion with some folk in linaro, I think I have this nailed. The names are updated to use the name on the front of the appropriate board user guide for the various baseboards, which I've taken to be the official name for each board. I haven't significantly updated the descriptions for the tiles as that is even less clear - as far as I can see on ARMs website, there is no Cortex-A9 tile for Realview EB - only ARM11MPCore, ARM1156T2F-S, ARM1176TZF-S and Cortex-R4F. So exactly what this 'Multicore Cortex-A9 Tile' is... Acked-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: 6201/1: RealView: Do not use outer_sync() on ARM11MPCore boards with L220Catalin Marinas2010-07-02
| | | | | | | | | | | | | RealView boards with certain revisions of the L220 cache controller (ARM11* processors only) may have issues (hardware deadlock) with the recent changes to the mb() barrier implementation (DSB followed by an L2 cache sync). The patch redefines the RealView ARM11MPCore mandatory barriers without the outer_sync() call.

* ARM: RealView: Fix typo in the RealView/PBX Kconfig entryCatalin Marinas2009-12-09

* RealView: Add sparsemem support for the RealView PBX platformCatalin Marinas2009-11-05
| | | | | | | | | | | | | | 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: Allow access to the secure flash memory block on PB1176Catalin Marinas2009-05-30
| | | | | | | | | | | | | | | | | | This patch adds a Kconfig option for specifying whether Linux will only be run in secure mode on the RealView PB1176 platform. Enabling it will make the secure flash memory block (64MB @ 0x3c000000) available to Linux. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

| * RealView: Allow PHYS_OFFSET at 0x70000000Catalin Marinas2008-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.
