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.
