After following your instruction, I tested fec_8xx
driver on RPXlite DW.
Changes were made as follows:
1. Mask __fw_getenv and 'ethaddr' code in
fec_8xx-netta.c to avoid compiling error 'undefined
reference to __fw_getenv';
2. Replace NETTA as RPXLITE in ..fec_8xx/Makefile &&
Kconfig;

Yeah, the result is so close to work right on RPXlite
DW. So great, a lot improvement. But still a pity...
