David, I prefer to have two patch for this. One is the CMD_MII support The second is the extend UEC to 4.
No problem. Will split the patch. Merging is on you though :) Regarding the MII support: This will include also a fix in the TSEC driver to enable it to address all MII addresses on the bus, regardless of the port (as someone asked here).
I don't like so much CFG_ option for the driver, which cause too many CFG_UEC[x]_NUM_TX_RX_THR in config.h. for every board.
and I think the threads number is not belonged to board specific
things.
The u-boot don't need to consider the UEC performance.
The default 4 threads should work for you. If it doesn't work for you, I suggest you keep the changes only for
your
project.
I don't know if you can agree it.
So, please repost the UEC_ETH4 support patch.
Regarding the thread number: As each UEC requires 8+ threads (4 for tx, 4 for rx), extending the number of UECs to 4 will exceed the number of QE threads. Now, 4 threads per TX/RX is only required for the GBE UEC. FE only requires one thread. So I'll change the driver in a way that it will use 4+4 threads in case of GBE, and 1+1 in case of FE. I already tested it here - and it worked fine. This way we won't need these CFG options per UEC any more. Is this ok?
David.
