I'm going to compile embedded power pc linux for a custom hardware. I use the Denx ELDK. The Linux Kernel configuration (make menuconfig) asks what machine type to compile Linux for. So I have the problem that I do not know which option to choose ("none" is not an option in the dialogue) and that I also do not know what choosing one of the existing options actually changes behind the scenes. I'd like a Linux to drop out that supports my MPC875 chip, works with the LXT 970A ethernet PHY chip and (if possible) the ISP1301 USB-on-the-go USB chip the board has and supports a serial terminal via SCC4 via the RXD4/TXD4 signals.
Any hint will be appreciated, best regards, Peter Asemann
