using u-bbot with new platform
Hello.
I'm a newbye in u-boot, i will use it in a hardware platform based in PXA255, iwill try to get ready the basic stuff, flash, RAM, uart, i will base it on any PXA255 board that already supported by u-boot.
My problem is that my hardware don't have a ethernet card, and it will be very usefull in the development process, i have a pcmcia card that is a tunlip_cs linux driver i think porting it, but i not have idea of what kind of considerations i need to taek in mind for pcmcia based card. If there anybody that try this, or another pcmcia card that have better support in u-boot, please help me.
Regards.

I don't have any answers on the PCMCIA issue, but one other option that may be useful is to load images from a MMC card. A MMC interface is very easy to get working (3 wires).

So is now the number of wires a measure for the complexity of a protocol hierarchy? I'm somewhat surprised.
