We'll have at = least three kernels though: armv4 little endian, armv4 big endian and = armv6 little endian. Even for atmel, some of the id registers are such = we may need multiple kernels. I guess they all use same interrupt controller. Currently there can be only support for one intc built in kernel so that = needs serious rework. Damjan
