The dtb passed by the CFE firmware has a number of issues, which up till now have been fixed by use of patches applied to the mainline kernel. This occasionally causes problems with changes made to mainline. Patching the firmware to correct the dtb is not an option for the following reasons: It was modified by a 3rd party, and we don't have a copy of the source. All versions of CFE used on the X1000 export the same dtb. At least one machine suffered damage during a firmware upgrade attempt, many people will be unwilling to reflash their system if an upgrade is produced. ... Pasemi arch code finds the root of the PCI-e bus by searching the device-tree for a node called 'pxp'. But the root bus has a compatible property of 'pasemi,rootbus' so search for that instead. ... The device tree on the Nemo passes all of the i8259 interruts with numbers between 212 and 222, and points their interrupt-parent property to the pasemi-opic, requiring custom patches to the kernel. Fix the values so that they can be controlled by the generic ppc i8259 code.
