    The PRCMU driver is only available on the UX500 platforms so building
    on x86_64 does not make sense.

    Ola/Mark: a simple patch like this should solve the issue I think?

    diff --git a/sound/soc/ux500/Kconfig b/sound/soc/ux500/Kconfig
    index 9b0ae4e..f454f06 100644
    --- a/sound/soc/ux500/Kconfig

    menuconfig SND_SOC_UX500

    help
    Say Y if you want to enable ASoC-support for
    any of the Ux500 platforms (e.g. U8500).

    But it seems it has a wider dependency on some MOP500 board
    stuff being merged first, which is more of a problem I think, part
    of that is pending in the Ux500 tree.

    Yours,
