This is you changing QEMU to not compile a file that was previously always compiled. If you do that then it's not surprising if things might break when you move to an upstream version, that's all. Ideally we'd have more CONFIG_SOME_DEVICE and CONFIG_SOME_BOARD checks here the way we do for the more recent boards like the Xilinx and iMX ones, then you could disable boards you didn't want in the config file. thanks -- PMM
