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.

C6X: early boot code

2011-10-06T23:47:28+00:00

Original port to early 2.6 kernel using TI COFF toolchain.
Brought up to date by Mark Salter 

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.
