What you need to do:
- export ARCH=arm
Then you can look at default configs for supported boards. Cf. 
arch/arm/configs/integrator_defconfig for example. If this matches the board 
you have you can do a 'make integrator_defconfig'.

Also 'make menuconfig' can help: in the menu, you need to select your system 
type in 'System Type ---> ARM System Type', then the platform type.

Note: lists.arm.linux.org.uk is not in use anymore.

I hope this helps,
