You could do like in my mainline patch, add the options to a specific
am335x file (I used /include/configs/ti_am335x_common.h). What tree
are you building from?

This option puzzled me too, hadn't thought this was possible, mostly
because in the boot sequence it seems like the environment is loaded
after the autoboot prompt.
I haven't tried it yet, but if you got the full source tree look for the
autoboot documentation in README and doc/README.autoboot.
In Denx's master you can use the env vars "bootdelaykey" or
"bootstopkey" to disable "any key" autoboot abort. But be sure u-boot is
built with CONFIG_AUTOBOOT_KEYED defined or else these options will not
be enabled.
Environment vars are what can be used at boot time to define how u-boot
should commence booting the OS, besides the options set at compile time.
The environment is read from the uEnv.txt file residing besides MLO and
u-boot typically on eMMC/flash or the SD-card. Normally BBB first tries
the eMMC, then SD. If the boot switch is depressed at powerup (not
reset) eMMC is skipped (actually SPI is tried instead) and u-boot on
the SD-card is used.
Anybody know if these options are available and enabled in u-boot on the
stock BBB images?
