eldk: compiling linux for custom hardware

[Peter Asemann]

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

You will have to port the  Linux  kernel  for  your  hardware,  which
includes adding appropriate entries to the config menues.

It will most certainly result in a configuration which is  wrong  for
your board.

You will have to create a port (more exactly: a configuration) of the
Linux kernel for your board.


[Note: this has nothing to do with the DENX ELDK -- your  subject  is
somewhat misleading.]
