Hi
I've scanned the patch briefly and have some comments below.

This patch just supports boot into u-boot from mmc or spi-nor flash. It just implements console, iomux and clock. There are no ethernet, nor-flash, mmc or other peripheral drivers.

Is imx51 really the name of this board? Later on it looks like the name is MX51_BABBAGE.

Since it's very likely that setup_nfc() and setup_uart() will be used in other i.MX51 boards as well it's a good idea to place these functions in cpu/arm_cortexa8/mx51/devices.c (or something similar).

- 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.
