This patch adds code to lib to enable sharing of useful OPTEE code between board-ports and architectures. The code on lib/optee/optee.c comes from the TI omap2 port. Eventually the OMAP2 code will be patched to include the shared code. The intention here is to add more useful OPTEE specific code as more functionality gets added.
