I'm also interested whether Xilinx EMAC or TEMAC ethernet driver is
supported in this...(after reviewing the Xilinx zip file, it doesn't...
sigh).

However, I do DO have an Ethernet driver for Xilinx EMAC and TEMAC for
U-boot and it works...   Unfortunately, it uses Xilinx copyrighted
codes...  Somehow, I doubt this is what you wanted.

Is Xilinx copyright ok with you?

Careful.  ML403 reference design (as-is) is not using the Xilinx option
of using side-by-side data access (32-bit fetch out of a single 16-bit
flash), so XIP (execution in place) is evidently NOT supported in ML403.
 However, I had a new bit file built with side-by-side data access
enabled, but haven't yet execute out of flash (no need because ML403 has
a big memory.)  But it correctly fetches 32-bit now.  Ping me in a week
on my progress with XIP and flash.
