Commit 07e461cd7e
"of: Ensure unique names without sacrificing determinism"
caused a boot failure regression on the Integrator machines.
The problem is probably caused by fiddling too much with
the device tree population in the OF init function, such
as passing the SoC bus device as parent when populating
the device tree.
This patch fixes the problem by:
- Avoiding to explicitly look up the tree root
- Look up devices needed before device population from
the match only, passing NULL as root
- Passing NULL as root and parent when calling
of_platform_populate()
After this the Integrators boot again. Tested on
Integrator/AP and Integrator/CP.

On exynos mcpm systems the firmware is hardcoded to jump to an address
in SRAM (0x02073000) when secondary CPUs come up. By default the
firmware puts a bunch of code at that location. That code expects the
kernel to fill in a few slots with addresses that it uses to jump back
to the kernel's entry point for secondary CPUs.
Originally (on prerelease hardware) this firmware code contained a
bunch of workarounds to deal with boot ROM bugs. However on all
shipped hardware we simply use this code to redirect to a kernel
function for bringing up the CPUs.
Let's stop relying on the code provided by the bootloader and just
plumb in our own (simple) code jump to the kernel. This has the nice
benefit of fixing problems due to the fact that older bootloaders
(like the one shipped on the Samsung Chromebook 2) might have put
slightly different code into this location.
Once suspend/resume is implemented for systems using exynos-mcpm we'll
need to make sure we reinstall our fixed up code after resume. ...but
that's not anything new since IRAM (and thus the address of the
mcpm_entry_point) is lost across suspend/resume anyway.

Currently, the thermal quirk is skipped only if the SoC revision is known to be
one that does not need them, but if the SoC revision cannot be obtained, the
quirk is applied assuming it's needed.
However, this quirk must be applied only we are sure the SoC needs it, for it
breaks the thermal support if applied on a SoC that doesn't need it. The reason
for this is that the quirk consists in changing the thermal devicetree
compatible string and register offsets, to workaround a hardware bug in the
early SoC revision.
Such changes are wrong if the SoC is a new revision and doesn't need
the workaround. Therefore, this commit changes the behavior, by
requiring the SoC revision to be known in order to peform a quirk.

This commit implements CPU hotplug support for the Marvell Armada XP
platform. The CPU hotplug stub functions from hotplug.c are moved into
platsmp.c, as it doesn't make much sense to have a separate file just
for these two functions.
In addition, this commit:
* Implements the ->cpu_die() function of SMP operations by calling
armada_370_xp_pmsu_idle_enter() to enter the deep idle state for
CPUs going offline.
* Implements a dummy ->cpu_kill() function, simply needed for the
kernel to know we have CPU hotplug support.
* The armada_xp_boot_secondary() function makes sure to wake up the
CPU if waiting in deep idle state by sending an IPI. This is
because armada_xp_boot_secondary() is now used in two different
situations: for the initial boot of secondary CPUs (where CPU reset
deassert is used to wake up CPUs) and for CPU hotplug (where an IPI
is used to take CPU out of deep idle).
* At boot time, we exit from the idle state in the
->smp_secondary_init() hook.
This commit has been tested using CPU hotplug through sysfs
(/sys/devices/system/cpu/cpuX/online) and using kexec.

The CPU hotplug code will need to call into PMSU functions to enter
and exit from deep idle states. However, the deep idle state is
currently entered by a function called do_armada_370_xp_cpu_suspend()
whose name really suggests it's an internal function, but we need to
export it to other files in mach-mvebu.
Therefore, this commit:
* Merges the code of do_armada_370_xp_cpu_suspend() into
armada_370_xp_pmsu_idle_prepare(), into a single function called
armada_370_xp_pmsu_idle_enter(), which prepares the PMSU for deep
idle, and then enters the deep idle state. This code will be common
to both cpuidle and CPU hotplug.
* For symetry, it renames the armada_370_xp_pmsu_idle_restore()
function to armada_370_xp_pmsu_idle_exit().
We also remove the 'noinline' qualifier for these functions, which
apparently had no reason to be here.

As Mainlining effort for SolidRun CuBox has been carried out on the
Engineering Sample, the board DTS was reflecting this. Actually,
SolidRun CuBox comes in three different variants:
Engineering Sample (ES), production with 1GB RAM (1G),
and production with 2GB RAM (2G).
Therefore, we base current dove-cubox.dts on to the 1G production
variant and add a ES dts to add required quirk for misrouted SDHCI
card detect on top of dove-cubox.dts. For the 2G variant we rely on
the bootloader to setup correct RAM size.
