This patch adds support for the TMS320C6678 SoC on an EVMC6678LE
evaluation board. The 6678 is a C66x family CPU which is very similar
to the already supported C64x CPUs with the addition of floating point
instructions.

Commit ccbc60d3 requires CPU
topology information even in !SMP cases. This requires C6X to
add a call tp register_cpu() in order to avoid a panic at
boot time.

Original port to early 2.6 kernel using TI COFF toolchain.
Brought up to date by Mark Salter <msalter@redhat.com>

This patch provides the early boot code for C6X architecture. There is a
16 entry vector table which is used to direct reset and interrupt events. The
vector table entries contain a small amount of code (maximum of 8 opcodes)
which simply branches to the actual event handling code.

The head.S code simply clears BSS, setups up a few control registers, and calls
machine_init followed by start_kernel. The machine_init code in setup.c does
the early flat tree parsing (memory, commandline, etc). At setup_arch time, the
code does the usual memory setup and minimally scans the devicetree for any
needed information.
