These patches support for the AM34 CPU core variant of the MN10300 arch. This
is an SMP capable core, so SMP support is added also.
Further, support for the MN2WS0060 processor (which is AM34 based), and the
ASB2364 evaluation board are added to make use of that.
There are three patches here that touch code outside of the arch:
(#1) A patch to revert parenthesisation of numbers in asm-offset.h which
breaks the MN10300 assembly code.
(#6) A patch to typedef the smpcall function pointer as it's used in many
places.
(#36) Some changes to the SMSC 911x driver to provide it with hooks by which it
can initialise the ASB2364 board FPGA and find the MAC address in an
alternate location.
