Is this a potential problem for other 440EPx boards as well? Or is it really 
only DU440 specific?

Hi Stefan,

this might touch other boards as well. A patch for our PMC440 will come up 
later today. 

I have a support case with AMCC about this and ask them If I shall provide a 
patch for sequoia as well. I expect that someone will contact you about this
issue.

You might want to switch to the 4xx-GPIO initialization via the 
CFG_4xx_GPIO_TABLE define at some time. This makes it much easier to 
configure the GPIO's correctly.

But if you don't want to do this right now, I can apply this current patch for 
now as a bug fix.

Best regards,
Stefan

[U-Boot] [PATCH 2/4] ppc4xx: Fix DU440 GPIO configuration

[Matthias Fuchs]

Hi Stefan,

I am aware of the CFG_4xx_GPIO_TABLE feature. I think there is also 
a TODO comment for this in my code. But right now I want to keep it as it is
because of a lack of time.

OK, makes sense to me. I'll push your patches to the master branch for 
upstream merge later.
