    ARM: Allow SoCs to enable scatterlist chaining · 74facffe
    Russell King authored
    Allow SoCs to enable the scatterlist chaining support, which allows
    scatterlist tables to be broken up into smaller allocations.
    
    As support for this feature depends on the implementation details of
    the users of the scatterlists, we can't enable this globally without
    auditing all the users, which is a very big task.  Instead, let SoCs
    progressively switch over to using this.
    
    SoC drivers using scatterlists and SoC DMA implementations need
    auditing before this option can be enabled for the SoC.
