It turns out that the logical CPU mapping is useful even when !CONFIG_SMP
for manipulation of devices like interrupt and power controllers when
running a UP kernel on a CPU other than 0. This can happen when kexecing
a UP image from an SMP kernel.
In the future, multi-cluster systems running AMP configurations will
require something similar for mapping cluster IDs, so it makes sense to
decouple this logic in preparation for this support.

PDMA controllers when instantiated from device tree are registered using
amba_device_register(). The registration process enables clock to the
controllers to read the peripheral id of the PDMA amba device.
In case of Exynos4, the clocks to the PDMA controllers are named as 'dma'
but amba_device_register() looks up the clock using the name 'apb_pclk'.
Hence, alias clocks with name 'apb_pclk' clock are created for clocks
with name 'dma'.

and SPI interrupts are relocated to start from 16 and 32 of the linux
irq space. This is a required to add device tree support for GIC and
Interrupt combiner for EXYNOS4.
A new macro 'IRQ_TIMER_BASE' specifies a platform specific base of the
linux virq number for the timer interrupts. For exynos4, this base is
set to end of the linux virq space. For the other S5P platforms, the
existing base '11' is retained.

bothersome to maintain and likely to lead to merge conflicts.
This patch moves the knowledge of which platforms are SMP-capable
to the individual machines. To enable this, a new HAVE_SMP config
option is introduced to allow machines to indicate that they can
run in a SMP configuration.

Making CACHE_L2X0 depend on (huge list of MACH_ and ARCH_ configs)
is bothersome to maintain and likely to lead to merge conflicts.
This patch moves the knowledge of which platforms have a L2x0 or
PL310 cache controller to the individual machines. To enable this,
a new MIGHT_HAVE_CACHE_L2X0 config option is introduced to allow
machines to indicate that they may have such a cache controller
independently of each other.
Boards/SoCs which cannot reliably operate without the L2 cache
controller support will need to select CACHE_L2X0 directly from
their own Kconfigs instead. This applies to some TrustZone-enabled
boards where Linux runs in the Normal World, for example.
