[Cbe-oss-dev] ps3.dts and /spu-isolation node

[graf_chokolo graf_chokolo]

Thanks, it worked :-)

First i booted my PS3 Linux, converted my /proc/device-tree with dtc to DTS
file, added /spu-isolation node, then created a DTB file with dtc, bootet
petitboot again and passed my new DTB file to kexec with option
--devicetreeblob. And it works now :-)
