[U-Boot] u-boot on c6x CPU ( texas instruments c6000 )

[Dmitry Bondar]

Can i share patches for start u-boot on tms320c6745 processor
(http://www.ti.com/product/tms320c6745)?
What is the best way?
May be somebody already make support c6000 (c6x) arch in u-boot?
For information:
C6X family of processors supported by gcc from version 4.7.0.
C6745 pin compatible with AM1705 (http://www.ti.com/product/am1705),
only CPU core is different, because drivers for davinci work ok on
c6745.
I'm work on this SOM http://inmys.ru/?_=/products/som_c6745
Now work: uart, nand, ethernet (drivers/serial/ns16550.c,
drivers/mtd/nand/davinci_nand.c, drivers/net/davinci_emac.c)

Yes you can share patches.

> What is the best way?

Use "git send-email" and send them to this list.

Is it really a self-standing architecture?

So it's not ARM I take it?

Nice going! Please share the patches :-)

Yes. Support for it has been added in gcc 4.7, see
http://gcc.gnu.org/gcc-4.7/changes.html. It is a DSP architecture, and
has its own instruction set.
