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.

Currently, when _request_firmware() fails to find the firmware
from the default /lib location, a couple of error messages are
printed denoting the same. Change the print level for these
messages from dev_warn to dev_dbg as it is fairly common to
have the user-space helper loading the firmware for us.
