Network (FEC) and SD controller (fsl_esdhc) are supported.

We should use MX51EVK instead.

- The MX51 3stack board seems to have a hardware
"peculiarity" confirmed under
- U-Boot, RedBoot and Linux: the ethernet Rx signal is
reaching the CS8900A
- controller inverted. The controller is capable of
detecting and correcting
- this, but it needs 4 network packets for that. Which
means, at startup, you
- will not receive answers to the first 4 packest, unless
there have been some
- broadcasts on the network, or your board is on a hub.
Reducing the ARP
- timeout from default 5 seconds to 200ms we speed up the
initial TFTP
- transfer, should the user wish one, significantly.
These comments do not apply to MX51EVK as there is no CS8900 controller on this board. Please remove.

'BBG' should be removed as we are no longer using the term Babbage.
I will also send you new optimized values for the DDR settings when I come back to the office.
