Liu Hui-R64343 - Feb. 23, 2011, 7:26 a.m.
This patch add initial support for freescale MX53LOCO board.
Network(FEC),SD/MMC, UART have been supported by this patch.

Signed-off-by: Jason Liu <r64343@freescale.com>

---
Changes for v2:
- remove config.mk, instead add CONFIG_ options in boards.cfg
- fix copyright issue, use freescale copyright.
- rebase on u-boot-imx/next branch and resend.

Hi Jason,

I had no comments about your patches, but since the window is still
closed I cannot merge them into u-boot-imx (master branch) and send a
pull for them. However, as I already did for other patches, I will merge
your patches into the next branch of u-boot-imx, so they will be ready
when the window is open again.

Best regards,
Stefano Babic

My review comments to v1 of this patch still apply.

Best regards,
