[U-Boot-Users] LL_TEMAC on Avnet MiniModule-FX12

> What repository are you working from?
U-Boot 1.3.1 cloned last February.

> What ML403 patch are you referencing?
http://www.dave.eu/download/misc/mmfx12/ml403.patch
This derives directly from this old patch that has been around since 2005:
http://www.dave.eu/download/misc/mmfx12/4-ml403.2005-10-01.patch
This patch has been applied by my colleague. Then I put my hands on 
repository and started working on MiniModule port.

Thanks for your availability.

We did the same. First we worked on the ML403, then we ported our 
project to MiniModule that will be the base for the final application.
