After u-boot updated to 2016.1, when system boot, it enters the interactive commandline and can not autoboot for beaglebone: 
#################
U-Boot SPL 2016.01 (Jan 26 2016 - 17:49:08)

In interactive command line, run bootcmd can boot without problems

Ignore my previous reply

I bisected the u-boot codebase and found that the patch which broke beaglebone autobooting is http://git.denx.de/?p=u-boot.git;a=commit;h=755324c432f62306487786f89efce96398291a03

This was then fixed in http://git.denx.de/?p=u-boot.git;a=commit;h=7205442e621db54ea06c3bca2d793e1ae2214f9c

I backported this patch in http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?h=master-next&id=a46dc87c92b4cf3f56c17b6f1d6e53ed0583bc09
