You should not need to bring out the JTAG.

The build process for other FSL boards that require RCW (i.e. P5040) can 
create a single binary that includes RCW, PBI, and u-boot. 

BUT the T1040 right now does not have a build target that creates this 
binary! It seems FSL hasn't gotten about to creating it yet (not in mailine, 
not in patchworks, none in the FSL SDK).
