= Introduction =
The BSP improvements broadly focus on:
* Implementing correct cache configurations
* Enabling SMP environment

= Getting Started =
* Raspberry Pi 2 board is required.
* Compile the source for bsp=raspberrypi2 
* It helps to run the simple "hello world" first. Next try running the RTEMS Kernel Image(RKI) and then the benchmarks included there.
The RKI package can be obtained from [https://github.com/alanc98/rki here]
 
= Implementing correct cache configurations =
Identified that caches were disabled, which is default state after reset. 
* Enable caches with CP15 
* Correct routines to setup mmu/cache  
* Implement cache coherency support 
* Test performance improvements with benchmarks(from the RKI package) 

= Enable and test SMP environment =
* Adding the necessary BSP hooks
* Interprocessor interrupts to wake the other three cores
* Initializations for the other three cores
* Testing with smptests
