Oops, I ran a quick check earlier by grepping for "sun-top-ctrl" and
looking under drivers/reset, but assumed this driver wasn't merged yet
when nothing came up in the code. Thanks for the pointer.
It looks like the current driver will work for 40nm, but 65nm uses
different bit positions: RESET_CTRL bit 3 to arm, and SW_RESET bit 31
to trigger. I'll add a new "brcm,brcmstb-reboot-65nm" compatible
string to make this work.
Also, we'll need to take Guenter Roeck's register_restart_handler()
patch in order to build on MIPS.
