    Subject[PATCH 6.0 447/862] ARM: Drop CMDLINE_* dependency on ATAGS
    Date
    From: Geert Uytterhoeven <geert+renesas@glider.be>

    [ Upstream commit 136f4b1ec7c962ee37a787e095fd37b058d72bd3 ]

    On arm32, the configuration options to specify the kernel command line
    type depend on ATAGS. However, the actual CMDLINE cofiguration option
    does not depend on ATAGS, and the code that handles this is not specific
    to ATAGS (see drivers/of/fdt.c:early_init_dt_scan_chosen()).

    Hence users who desire to override the kernel command line on arm32 must
    enable support for ATAGS, even on a pure-DT system. Other architectures
    (arm64, loongarch, microblaze, nios2, powerpc, and riscv) do not impose
    such a restriction.

    Hence drop the dependency on ATAGS.

    Fixes: bd51e2f595580fb6 ("ARM: 7506/1: allow for ATAGS to be configured out when DT support is selected")
