[U-Boot-Users] Introduction->EMAC 5282 code release

[NZG]

The old 5282 stuff doesn't work all that well.(At least I could never get it 
too)
As far as that old post,
>(http://sourceforge.net/mailarchive/message.php?msg_id=11392569)
Zack is correct that the structure is wrong, but there are other problems with 
the old code as well.

We have modified u-boot to work correctly with our 5282 based module..perhaps 
you could incorporate it into your design instead of starting from scratch?

Regardless, the following link is a good place to start:
ftp://SoM:sompublic@ftp.emacinc.com
Here you'll find lots of stuff specifically for the 5282, including Zach and 
EMAC's u-boot code modifications. There's also datasheets for our SoM-5282EM 
module, which could certainly save you some time designing with the 5282.....

I'll try to break out individual stuff into patches and get it into the main 
tree at some point, but compatibility with the main source tree's flash 
drivers is still an issue as I understand it.

thx,  
NZG.
