it's all ADI written and owned.  we dont particularly care about the license, 
but i guess i can tag it GPL-2.

it's going to introduce a lot of whitespace churn ... i dont care, but i 
imagine you're going to complain when i fix existing files

it is the designed programming style for all low level Blackfin systems.  it 
is unified across Linux, U-Boot, bare metal code, and the official ADI 
propriety compiler.  i thought your point was to keep U-Boot and Linux the 
same at the API level so code sharing is very easy between it ?
