Michael Ellerman 61e8a0d5a0 powerpc/pci: Fix endian bug in fixed PHB numbering ... The recent commit 63a72284b1 ("powerpc/pci: Assign fixed PHB number based on device-tree properties"), added code to read a 64-bit property from the device tree, and if not found read a 32-bit property (reg). There was a bug in the 32-bit case, on big endian machines, due to the use of the 64-bit value to read the 32-bit property. The cast of &prop means we end up writing to the high 32-bit of prop, leaving the low 32-bits containing whatever junk was on the stack. If that junk value was non-zero, and < MAX_PHBS, we would end up using it as the PHB id. This results in users seeing what appear to be random PHB ids. Fix it by reading into a u32 property and then assigning that to the u64 value, letting the CPU do the correct conversions for us.
