[meta-ti] BeagleBone Black , u-boot, and zImage

[Carlos Rafael Giani]

Hello,

after building a rootfs for the Beaglebone Black, I see the following 
files in the deploy folder for the machine:

MLO
u-boot.img
u-boot-spl.bin
zImage

as well as other symlinks with "-beaglebone" attached to their filenames.

What should I copy, the SPL bin, or the .img u-boot binary?
Also, u-boot tries to load a uImage, even though a zImage was built. 
There is also no uEnv.txt file.
Do I have to write one to be able to let u-boot load the zImage, or 
should it work out-of-the-box?
