Participation in GSoC 2016

Great ! I will add this to my application. Parallely I was looking for
some other BSP like this. Looks like last year André added support for
SD card by adding the SDHCI and MMC/SD bus drivers from libBSD
successfully (https://devel.rtems.org/wiki/GSoC/2015/Final_Report#AndreMarques:RaspberryPiLowLevelPeripheralsandSDCard).
I will build anyone of them (arm/realview_pbx_a9_qemu or SD card) in
my acceptance waiting period and get familiarised with the build
process.

I think from my side my proposal is ready. You can have a look at
that. Kindly suggest if anything alse is missing.
