Hi all,
Sorry for late reply, I was out of office.

Looks fine, but can we get this tested on the isee board too? It's a functional change there (since it was setting the NOTUSED bit that HW folks say really should not be set and will be marked as reserved in the next TRM respin). Thanks!
With this patch the IGEP COM AQUILA works as expected. Thanks.

- changes for v2: defined all bits used in the gmii_sel register as Tom Rini suggested
- changes for v3: rebased against u-boot-ti commit bb2a5d8f87fffb4fadfb205837decbd1b3e75f88
- changes for v4:
- rebased against u-boot-ti commit 425faf74cd8189c87919f7e72a0101c684ee3b9f
- add changes requested from Tom Rini:
- use <space> after "#define" instead <tab>
- rename struct name "reserved" to "resv1"
- remove GMII1_SEL_NOTUSED and GMII2_SEL_NOTUSED defines, also the GMII2_SEL_NOTUSED usage on the igep0033 board
- add "Acked-by: Mugunthan V N mugunthanvnm@ti.com"
