It's the  real physical address.

Since vxWorks (5.4) has no virtual memory support and the exception
base address is mapped to 0x0 already, starting linux kernel at 0x0
would mean there is no exception handling capability at least at
the very beginning.

Why not? When you copy the Linux  kernel  image  to  low  memory  you
include the Linux trap handlers, of course.

Not that they would do you any good in the very early boot stage,
