So as part of GSoC 2015 I had to fix cache configurations and enable a stable SMP environment for Raspberry Pi 2.
With respect to cache configurations, though an improvement has been obtained, the issue of text section access permissions has to be solved completely. Some solutions can help escape the problem but not solve it completely. This matter has to be looked into post the program.
Next, in case of SMP support, I came across issues whose roots could eventually be identified. What needs to be done to get basic SMP working is something I could figure out and have tried to implement. However some problems persist and SMP still cannot be done on Pi 2. Post this edition of GSoC the necessary implementation hurdles have to be resolved and SMP enabled on Pi 2.
Interrupt handling for Pi 2 has to be set up and integrated with existing implementation.
Apart from the above, work remains to be done in relation to Pi 2 peripheral support.
I would certainly like to continue working with Raspberry Pi 2 BSP Support!
