What is the maximum byte size for 1 U-Boot environment variable?

Odd question, but how big can I make a U-Boot environment variable before it fails?

Essentially what type is a U-boot environment variable?

It depends slightly on what you're doing. The overall environment is limited to CONFIG_ENV_SIZE. The amount of text you can input at a given time is CONFIG_SYS_CBSIZE.
