[U-Boot] Hush - reading value from memory and setup variable

Hi all,

I have in memory string/values whatever and I would like to setup some u-boot variables based on it directly from HUSH

I mean for example to have there unique MAC addr and I would like to setup it in preboot. I am trying to find out any U-BOOT commands which could help me. But I am not sure if is even possible to do it directly from hush.

Writing any specific C code is easy.

Any ideas?

Thanks, Michal
