Yes.  But that is about the only similarity.  A basic BSP consists of  
board startup code and device drivers.

It differs per architecture.  Usually you use the OS device driver  
interface to talk to the devices, configure the system to start the BSP  
processes and you compile and link the BSP with the kernel.
