    I'm looking at some sources for kernel Execute-in-place (XIP).

    I see references to CONFIG_XIP_ROM and CONFIG_XIP_KERNEL,
    in different architecture branches of the same kernel
    source tree.

    Is this difference merely the result of inconsistent
    usage, or is there a functional difference between
    these two options?

    I can imagine that CONFIG_XIP_ROM is intended only to
    handle XIP in ROM, and that CONFIG_XIP_KERNEL possibly
    handles additional cases like XIP in flash. However,
    before jumping to that conclusion I thought I would
    ask if there is some intention behind the different
    config names.

    Thanks,
