That's this 4 line change.. ;) https://github.com/RobertCNelson/Bootloader-Builder/blob/master/patches/v2017.01/0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch#L821-L824 We pushed it mainline, lasted about two releases before a later change disabled it. > I have experience in creating custom boards in U-Boot and generally I could > have fix this simple phantom character problem by simply saving the proper > bootdelay environment variables in U-Boot during the manufacturing process. > But, the BeagleBone Black/Green use a uEnv.txt file for the environment > variables and it cannot be used for bootdelay.

Most of our patchset is to support 'stuff' we came up with before extlinux/distro_defaults went into u-boot mainline. Then we have support for board's in flight.. BeagleBone Green Wireless/BeagleBone Black Wireless, when those dts files get merged into linus' master tree for v4.11.0-rc1 i'll push them to u-boot master.. (they are staged in linux-omap right now) Then lots of "debug" enablement, from when we chased fun bugs..
