This patch is an RFC.
ns9750 was removed in commit 4cfc611b4a4ce009cfad46804bec2a1caad8e329, this is an attempt to make it work again. Comparing the files from removal revision and current, there are changes made in board/ns9750dev/ns9750dev.c and in include/configs/ns9750dev.h Currently this fails at linkage stage.
