[PATCH 00/29] Add Cavium OCTEON processor support (v3).

David Daney
2008-11-06T20:52:18Z

This patch set introduces preliminary support for Cavium Networks'
OCTEON processor family. More (but not detailed) information about
these processors may be obtained here:

http://www.caviumnetworks.com/OCTEON_MIPS64.html

This initial patch set adds support for booting an initramfs to a
serial console. Follow-on patch sets will add support for the on-chip
ethernet, USB, PCI, PCIe, I2c and other peripherals.

With this third version of the patches I think we have fixed or
removed most of the parts flagged as objectionable in the first two
rounds of reviews. There was extensive rearrangement of some of the
chip and board support files as well as cleanup of cache, dma, and
interrupt code. Ralf already merged or made equivalent changes for
six of the patches so the set is getting smaller.

I am sending 23 - 27 to linux-serial and linux-kernel and akpm in
hopes that these non-MIPS patches might be reviewed thus enabling the
entire set to eventually be merged.

29 patches to follow as replies (I hope).
