2012-01-25ARM: 7298/1: realview: fix mapping of MPCore private memory regionMarc Zyngier
Since commit 0536bdf33faf (ARM: move iotable mappings within the vmalloc region), the RealView PB11MP cannot boot anymore. This is caused by the way the mappings are described on this platform (define replaced by hex values for clarity): { /* GIC CPU interface mapping */ .virtual = IO_ADDRESS(0x1F000100), .pfn = __phys_to_pfn(0x1F000100), .length = SZ_4K, .type = MT_DEVICE, }, { /* GIC distributor mapping */ .virtual = IO_ADDRESS(0x1F001000), .pfn = __phys_to_pfn(0x1F001000), .length = SZ_4K, .type = MT_DEVICE, } The first mapping ends up reserving two pages, and clashes with the second one, which triggers a BUG_ON in vm_area_add_early(). In order to solve this problem, treat the MPCore private memory region (containing the SCU, the GIC and the TWD) as a single region, as described in the TRM: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0360f/CACGDJJC.html The EB11MP is converted the same way, even if it manages to avoid the problem. Tested on both PB11MP and EB11MP. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

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>
