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
These patches depend on the '[PATCH 0/4] serial: Patches for OCTEON
CPU support (version 2).' set that Alan Cox already has queued up.
They can be seen here:
http://www.linux-mips.org/cgi-bin/mesg.cgi?a=linux-mips&i=4934774E.6080805%40caviumnetworks.com
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
Compact Flash, ethernet, USB, PCI, PCIe, I2c and other peripherals.
With this fifth revision of the patches I think we have address all
the issues explicitly flagged as objectionable in the preceding
revisions. The major change is reformatting of code and comments in
the first two patches of the set. The only remaining checkpatch.pl
errors are due to that program's inability to handle MIPS assembly
language and inline asms. Quite a bit of unused code was also
removed.
21 patches to follow as replies.
