BeagleBone U-Boot GPIO Command

[Phishfry]

I have been experimenting with setting GPIO pin states in U-boot from the GPIO command.
It works well.

Beaglebone u-boot removed GPIO command from am335x_evm_defconfig. Been that way since 2021.
Not sure why.

To get the function back add this to /usr/ports/sysutils/u-boot-beaglebone/files/bbb_fragment

CONFIG_CMD_GPIO=y

Before the change = Error -19
After

=> gpio status -a
