Flashing U-Boot on the GL-AR300M

N.B. This was written from memory, so some steps might be missing/incorrect. Corrections appreciated!

The hidden page for flashing via the embedded webserver doesn't work, but flashing via serial triggered tftp works. This requires a serial to USB adapter (only TX/RX/GND are connected). See here for a pinout.

1. Go here to grab the latest U-Boot: https://us.gl-inet.com/forums/topic/ar-300m-upgrade-uboot-to-newer-verions/

1a. Downloading requires a new user registration. It's fairly painless (e-mail addr req'd).

The locale requested by LANG=en_US.utf8 isn't available here.
Running `locale-gen en_US.utf8' may be necessary.

mosh-server needs a UTF-8 native locale to run.

Unfortunately, the local environment ([no charset variables]) specifies
the character set "US-ASCII",

The client-supplied environment (LANG=en_US.utf8) specifies
the character set "US-ASCII".
