Considering this, it might be a good idea to remove support for PNX4008 (arch/arm/mach-pnx4008/) altogether. It's hard to maintain support for hardware which isn't available, even at NXP. It would also simplify maintenance of mach-lpc32xx because the overlap currently makes me always wonder if the respective changes still work with mach-pnx4008. Any opposition?
