Setting reboot type at run time for ARM

[Arun Ramamurthy]

Hello

I would like to specify a reset type just before issuing the reboot 
command in the kernel. I know the kernel command line parameter can be 
set as "reboot=w" to indicate warm reset but I want to be able to decide 
this at run time before issuing a reboot command. What would be the best 
way to implement this? Modify the reboot command
to accept a parameter or is there a standard hook I can use?
