[PATCH 14/41] ARM: restart: iop3xx: use new restart hook
Russell King - ARM Linux
linux at arm.linux.org.uk
Sun Nov 6 12:44:42 EST 2011
Hook these platforms restart code into the arm_pm_restart hook rather
than using arch_reset().
In doing so, we split out the n2100 platform specific restart handler
into the n2100 platform file.
