Add architecture support for the MN10300/AM33 CPUs produced by MEI to the kernel. This patch also adds board support for the ASB2303 with the ASB2308 daughter board, and the ASB2305. The only processor supported is the MN103E010, which is an AM33v2 core plus on-chip devices.

Kprobes allows you to trap at almost any kernel address and
|
|
execute a callback function. register_kprobe() establishes
|
|
a probepoint and specifies the callback. Kprobes is useful
|

for kernel debugging, non-intrusive instrumentation and testing.

If in doubt, say "N".

If you say Y here, it will be possible to remotely debug the kernel
|
|
using gdb. This enlarges your kernel ELF image disk size by several
|
|
megabytes and requires a machine with more than 16 MB, better 32 MB
|
|
RAM to avoid excessive linking time. This is only useful for kernel
|
|
hackers. If unsure, say N.
