Patches from Anders Berg applied individually:

Here is version 4 of platform support for AXM5516 SoC.

The clk driver is now applied to clk-next. The rest should be ready for
arm-soc. Haven't got any response from the power/reset maintainers... I hope
this driver can be taken via arm-soc as well.

The AXM55xx family consists of devices that may contain up to 16 ARM Cortex-A15
cores (in a 4x4 cluster configuration). The cores within each cluster share an
L2 cache, and the clusters are connected to each other via a CCN-504 cache
coherent interconnect.

This machine requires CONFIG_ARM_LPAE enabled as all peripherals are located
above 4GB in the memory map.

In the refactoring of the coherency fabric assembly code, a function
called ll_get_cpuid() was created to factorize common logic between
functions adding CPU to the SMP coherency group, enabling and
disabling the coherency.

However, the name of the function is highly misleading: ll_get_cpuid()
makes one think tat it returns the ID of the CPU, i.e 0 for CPU0, 1
for CPU1, etc. In fact, this is not at all what this function returns:
it returns a CPU mask for the current CPU, usable for the coherency
fabric configuration and control registers.

Therefore this commit renames this function to
ll_get_coherency_cpumask(), and adds additional comments on top of the
function to explain in more details what it does, and also how the
endianess issue is handled.

As part of the introduction of the cpuidle support for Armada XP, the
coherency code was significantly reworked, especially in the
coherency_ll.S file. However, when the ll_get_cpuid function was

the register was not updated properly.

The Marvell Armada 375 and Armada 38x SOCs, which use the Cortex-A9
CPU core, the PL310 cache and the Marvell PCIe hardware block are
affected a L2/PCIe deadlock caused by a system erratum when hardware
I/O coherency is used.

This deadlock can be avoided by mapping the PCIe memory areas as
strongly-ordered (note: MT_UNCACHED is strongly-ordered), and by
removing the outer cache sync done in software. This is implemented in
this patch by:

 * Registering a custom arch_ioremap_caller function that allows to
   make sure PCI memory regions are mapped MT_UNCACHED.

 * Adding at runtime the 'arm,io-coherent' property to the PL310 cache
   controller. This cannot be done permanently in the DT, because the
   hardware I/O coherency can only be enabled when CONFIG_SMP is
   enabled, in the current kernel situation.
