  To: linux-arm-kernel

This series lays down the ground work for changing the way we handle the
reset (now called restart) handling on ARM.

As a result of these patches, we provide a new hook in the machine_desc
record called 'restart' which is pointed at a function to perform the
appropriate restart actions for the platform.  This is called directly
from machine_restart() with IRQs and caches on.

The 'soft_reboot' flag is changed to a more generic 'restart_mode'
character - which is used to initialize the default reboot mode (which
can be changed via the 'reboot=' command line parameter.)

'soft_restart(addr)' is added which performs a soft restart (iow,
orderly shutdown of caches and MMU and a jump to the passed address),
rather than the old way which separated the tear-down of the caches
and MMU from the code doing the jump.  This will be necessary to
resolve the ARMv6 and ARMv7 CPU restarting problems.

Finally, appropriate 'restart_mode' values are added to several
platforms which were hard-coding the restart mode by intercepting
the restarting via arm_pm_restart.
