[U-Boot-Users] [PATCH] ppc4xx: Canyonlands: Disable PCIe port 0 in dev-tree when SATA is selected

[Stefan Roese]

When SATA is selected (via jumper J6) we need to disable the first PCIe
node in the device tree, so that Linux doesn't initialize it. Otherwise
the Linux SATA driver will fail to detect the devices.
