Specifies whether the Boot ROM code configures the
IOs used by boot after a warm reset. Note that the
Boot ROM code always configures the IOs used by
boot after a cold reset. After the Boot ROM code
configures the IOs used by boot, it always disables this
field. It is up to user software to enable this field if it
wants a different behavior.
