It's crazy how much weird stuff they're cramming into u-boot default
environments now.  It's almost like they're having some sort of "I'm
more clever than you with this primitive scripting language" contest.

I tend to go minimal, this is my typical u-boot env:

=> printenv
baudrate=115200
bootcmd=run ubmmc
bootdelay=2
fdt_file=wandboard-quad.dtb
loadaddr=0x11000000
loaderdev=net
ubmmc=fatload mmc 0 ${loadaddr} ubldr; bootelf
ubnet=dhcp ${loadaddr} /wand/boot/ubldr;bootelf

Environment size: 279/8188 bytes
