"E" probably, but the chip revision id should be a more accurate info.
- E means that the device supports power management features (not used for
now under Linux).
- J means that is supports JTAG
- N means JTAG support but not big-endian mode that is a never used
feature, I think.
- B addresses the package (208 pin plastic versus 169 blah blah ...)
- Etc ... I don't know the meaning about the other 22 possible letters.;-)
Things like J, JB, E, JE, JBE, ... exists.
The relationship between chip revision and actual chip type may just not
exist. I remind having asked Pamela Delanney from LSI LOGIC a couple of
months ago, but it was hard for her to gather the information.;) Further
sym/ncr driver versions will display 875 for everything that incorporates
one or two 875 cores, for simplicity and in order not to output wrong
info.
