[PATCH 06/10] ARM: Layerscape: icids: factor out setup_icid_offsets()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The code to iterate over the icid table writing register values can be
re-used for upcomin LS1028a support, so move the code to a separate
function.
