/* Some chip cannot support external ram with rwx attr at the same time,
it has to map it into 2 spaces of idbus and dbus, code in dbus can be
read/written and read/executed in ibus. so there are 2 steps to execute
the code, first, copy&do relocaiton in dbus space, and second execute
it in ibus space, since in the 2 spaces the contents are the same,
so we call it bus mirror.
