* C6X: add basic support for TMS320C6678 SoCKen Cox2012-07-181-0/+4
| | | | | | | | | | | | 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 callMark Salter2012-01-081-0/+15
| | | | | | | | | 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. Signed-off-by: Mark Salter <msalter@redhat.com>
* C6X: deal with memblock API changesMark Salter2012-01-081-3/+0
| | | | | | | | | | | | | | | Recent memblock related commits require the following C6X changes: * commit 24aa07882b672fff2da2f5c955759f0bd13d32d5 asm/memblock.h no longer required * commit 1440c4e2c918532f39131c3330fe2226e16be7b6 memblock_analyze() no longer needed to update total size * commit fe091c208a40299fba40e62292a610fb91e44b4e memblock_init() no longer needed Signed-off-by: Mark Salter <msalter@redhat.com>
* C6X: early boot codeAurelien Jacquiot2011-10-061-0/+498
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.
