This is the sixth revision of the 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 sixth revision of the patches I think we have address all the issues explicitly flagged as objectionable in the preceding revisions. The main change from the previous set is the addition of a clock source driver. Previously the clock source had been broken. 20 patches to follow as replies.
