c6x: convert fdt pointers to opaque pointers

2014-04-30T05:59:12+00:00

The architecture code does not need to access the internals of the FDT
blob, so make the pointer to it void *.

c6x: use boot_command_line instead of private c6x_command_line

2013-10-09T16:37:27+00:00

Save some pointless copying of the kernel command line and just use
boot_command_line instead.

Also remove default_command_line as it is not referenced anywhere, and
the DT code already handles the default command line.

C6X: add basic support for TMS320C6678 SoC

2012-07-19T03:52:31+00:00

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.

C6X: add register_cpu call

2012-01-08T20:13:10+00:00

Commit ccbc60d3e19a1b6ae66ca0d89b3da02dde62088b 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.
