16.05 printf test does not build for Cortex A9.

[robjsstewart at ...196...]

Now I see all the changes for Cortex A9 boards since the 15.11 release, the last one I cloned. The build works ok, now I need to understand the gory details.

Also, it appears that there is no cpu.h any more in the 
core/include/spec/cortex-a9 directory as the compile of the new region 
map fails as follows:

What have I missed?
