     11= Introduction =
     12The BSP improvements broadly focus on:
     13* Implementing correct cache configurations
     14* Enabling SMP environment
     15
     16= Getting Started =
     17* Raspberry Pi 2 board is required.
     18* Compile the source for bsp=raspberrypi2
     19* It helps to run the simple "hello world" first. Next try running the RTEMS Kernel Image(RKI) and then the benchmarks included there.
     20The RKI package can be obtained from [https://github.com/alanc98/rki here]
     21 
     22= Implementing correct cache configurations =
     23Identified that caches were disabled, which is default state after reset.
     24* Enable caches with CP15
     25* Correct routines to setup mmu/cache 
     26* Implement cache coherency support
     27* Test performance improvements with benchmarks(from the RKI package)
     28
     29= Enable and test SMP environment =
     30* Adding the necessary BSP hooks
     31* Interprocessor interrupts to wake the other three cores
     32* Initializations for the other three cores
     33* Testing with smptests
