ColdFire: Relocate vector table - mcf5445x
Newer ColdFire processors family boot from address 0 instead of 0xFFnn_nnnn. When the boot flash base chip select is set at new location instead of 0, an un-predictable error will occur if there is an vector being trigger and refer it to an invalid address or the vector table handler is not existed at address 0.
