[U-Boot] [PATCH v3 3/6] ARM: Add macros.h to be used in assemblerfile.

[Peter Pearse]

Magnus

	Please ensure when writing ARM macros that any  architecture
specific instructions are

restricted to the correct architecture. 

This patch should be OK, this is just a heads up for any budding macro
writers on the list

Regards

Peter
