I found E2END in this directory and file:
C:\Program Files\Atmel\AVR Tools\AvrAssembler2\Appnotes\m8def.inc
It is NOT in this file
C:\Program Files\Atmel\AVR Tools\AvrAssembler\Appnotes

Note the "2" in the pathname for the former, not the latter.
Go figure.

I would hazard a guess that  E2END is value equivalent to the last 
location of the EEPROM. I am not sure if this is an Atmel define or a 
complier one.
