Hi, I'm trying to port U-boot to our board based on the ls1020a processor. I've started modifying a copy of include/configs/ls1021atwr.h. What I would like to know is if there's any documentation for the config items that are not in the README, especially the eTSEC section? Thanks.
TSEC-related options are pretty self-explanatory. The main option is CONFIG_TSEC_ENET,
which I guess you have already found in the README. If not, check
doc/README.mpc85xxads. The best way to understand the rest is to
look at the source. There are only a few files besides configuration headers under
include/config/ where they appear. The most important are
drivers/net/tsec.c which covers the main TSEC functionality and files
under /board/freescale/ which deal with pin and protocol multiplexing.
If any option meaning remain unclear, do not hesitate to ask more specifically.
