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).
