These all look very similar and should be combined. Why do you not have
1 machine for all DT platforms as other SOCs are doing?

This needs to be rebased for the latest kernel.
Which looks like this:

MACHINE_START(U8500, "ST-Ericsson MOP500 platform")
        /* Maintainer: Srinidhi Kasagar [off-list ref] */
        .atag_offset    = 0x100,
        .map_io         = u8500_map_io,
        .init_irq       = ux500_init_irq,
        /* we re-use nomadik timer here */
        .timer          = &ux500_timer,
        .init_machine   = mop500_init_machine,
MACHINE_END

MACHINE_START(HREFV60, "ST-Ericsson U8500 Platform HREFv60+")
        .atag_offset    = 0x100,
        .map_io         = u8500_map_io,
        .init_irq       = ux500_init_irq,
        .timer          = &ux500_timer,
        .init_machine   = hrefv60_init_machine,
MACHINE_END

MACHINE_START(SNOWBALL, "Calao Systems Snowball platform")
        .atag_offset    = 0x100,
        .map_io         = u8500_map_io,
        .init_irq       = ux500_init_irq,
        /* we re-use nomadik timer here */
        .timer          = &ux500_timer,
        .init_machine   = snowball_init_machine,
MACHINE_END

So - different .init_machine() calls, needed to simplify the board
files as of now. (Patch from Lee Jones.)
