Bad idea. That address may not be mapped at all, or not at the  right
physical  address.  Also,  just  jumping to a boot loader entry point
does not cause a hardware reset, so any devices that might  be  stuck
will remain stuck.

You should always try to  cause  a  real  reset;  there  are  several
methods  in  use  for  this,  like  using a watchdog reset, causing a
machine check, etc. Just see existing code.

Best regards,
