In a heterogenous multiprocessor system, specifying the
'maxcpus' parameter on the kernel command line does not
provide sufficient control over which CPUs are brought
online at kernel boot time, since CPUs may have nonuniform
performance characteristics. Thus, we introduce a
'boot_cpus' command line argument, allowing the user to
explicitly specify the list of CPUs that shall be brought
online during kernel boot.

Existing PSCI implementation supports platform coordinated means of low
power modes where cluster low power modes are aggregated at the platform
level. Adding support for OS initiated scheme, where is OS is responsible
for selecting cluster low power modes based on last man determination. With
OS initiated scheme, the OS can make better cluster decisions based on
wakeup times of CPUs within a cluster.
To this effect, in OS initiated schemes, the composite state ID is computed
by the idle driver before calling into the cpu_suspend API. The PSCI driver
is modified to use the composite ID to distinguish between retention and
non-retention states.

the non-sec interrupts at QGIC by setting the GRPEN1_EL1_NS
to ZERO. This makes core not seen any non-sec interrupts
and would result into system do not wake up from any of

Change-Id: I3441873eb4009b105db04f4a18d28ae9ccd07e95
Cluster pm notifications without level information increases difficulty
and complexity for the registered drivers to figure out when the last
coherency level is going into power collapse.
Send notifications with level information that allows the registered
drivers to easily determine the cluster level that is going in/out of
power collapse.
There is an issue with this implementation. GIC driver saves and
restores the distributed registers as part of cluster notifications. On
newer platforms there are multiple cluster levels are defined (e.g l2,
cci etc). These cluster level notofications can happen independently.
On MSM platforms GIC is still active while the cluster sleeps in idle,
causing the GIC state to be overwritten with an incorrect previous state
of the interrupts. This leads to a system hang. Do not save and restore
on any L2 and higher cache coherency level sleep entry and exit.
