    ARM: dts: Disable smc91x on n900 until bootloader dependency is removed · b16ccfe0
    Tony Lindgren 提交于
    I added smc91x support but turns out we currently do not set the
    smc91x timings in gpmc.c but rely on the bootloader timings. This
    produces the following error unless the smc91x GPMC timings are
    initialized by the bootloader:

    Let's fix the issue by disabling the smc91x module for now until we
    have sorted out the issues in gpmc.c.
