Same question for me but I want instead to access ppcboot environment stored
in flash.

What kind of storage are you interrested in?
I wrote a kernel driver to access PPCBoot environment variables stored
in a M24C32-W EEPROM, connected through I2C bus.
It allows raw access through /dev/eeprom, couple of ioctl's (setenv, getenv,
unset, etc.), and content reading for shell scripting (through /proc file).

ask me

sure. I may have to clean up a bit though, and issue a nice patch.
