Will Deacon e6ee4b2b57 ARM: 7607/1: realview: fix private peripheral memory base for EB rev. B boards
Commit 34ae6c96a6 ("ARM: 7298/1: realview: fix mapping of MPCore
private memory region") accidentally broke the definition for the base
address of the private peripheral region on revision B Realview-EB
boards.

This patch uses the correct address for REALVIEW_EB11MP_PRIV_MEM_BASE.

Marc Zyngier 34ae6c96a6 ARM: 7298/1: realview: fix mapping of MPCore private memory region
Since commit 0536bdf33f (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.

Catalin Marinas ee8c957119 RealView: Move the IRQ_* definitions out of the board-*.h files
The IRQ_* macros need to be made visible via the mach/irqs.h file but
without the additional macros defined in the board-*.h files.

Catalin Marinas 1bbdf637ba RealView: Clean up the machine_is_*() calls in platsmp.c
Some of the calls weren't necessary and some others were duplicated.
This patch tidies up the platsmp.c file.

Catalin Marinas ebac6546df RealView: Use only the shadow mapping of ARM11MPCore local timers
All the cases where the local timer for a CPU is accessed happen on the
corresponding current CPU, hence no need to access the per-CPU local
timer mappings.
