Please check the list archives, this is really a FAQ. I build one
myself, you can get it at
http://www.lart.tudelft.nl/lartware/compile-tools/
You can get another one (more complete with all GCC compilers) at

You need a cross compiler (or another native ARM platform) to get the
machine to work at all. There is no such thing as a generic ARM kernel
that boots on all ARM platforms.
AFAIK you don't need a compiler that emits v5 instructions; lower
levels will work, but with a little loss of speed.

Hmm, the GCC CVS snapshots are not suited for compiling kernels. There
are things that are known to break. The current consensus on the
linux-kernel mailing list is that compiling with GCC snapshots is only
encouraged to get the kernel compatible with the compiler. Maybe
Russell or Phil can comment on the usage of GCC snapshots on ARM?

But does it run? The GCC snapshots are known to break the kernel in
subtle ways.
