> Hello,
> 
> I'm planning on using Compact Flash on an MPC8349 in True IDE mode, but
> only have one chip select line available.  The local bus on this chip is
> for all intents and purposes the same as all of the 8xx/82xx chips that
> came before it.  The plan is do some address decoding magic in a CPLD to
> provide two indirect chip selects.  
> 
> Browsing through the U-boot code and some other boards using True IDE, I
> think this should work without much drama.  Does anyone have comments or
> suggestions?
