    This feature is implemented on some systems using an IPMI OEM command:
    https://github.com/openbmc/google-ipmi-sys#delayedhardreset---subcommand-0x03
    
    It currently just activates the systemd target
    gbmc-psu-hardreset.target and lets you register services to do the
    actual hotswap reset (usually by toggling a GPIO). Having a unified
    solution in x86-power-control for this would be great!

Ben, Can you please share content of
 https://github.com/openbmc/google-ipmi-sys/blob/master/gbmc-psu-hardreset.target
as my assumption is each platform needs to provide this file but I couldn't find any platform
using this. I only found reference in meta-quanta which is deleting this file. So please
provide a reference to this file.
