Thanks. So what I get is that there is no term such as "Embedded Linux
Kernel". There are embedded distributions however, that contain kernel
(compiled for an embedded architecture) with specific patches (by the
ditribution vendor) for the specific embedded platform (ARM / PPC
etc).

But CAN I run standard stock kernel compilerd for an embedded chip
(say ARM) on an ARM processor? Or do I NECESSARILY need the patches by
the distribution?

Thanks,

Dan
