    Date
    From: Geert Uytterhoeven <geert+renesas@glider.be>

    [ Upstream commit 2eced4607a1e6f51f928ae3e521fe02be5cb7d23 ]

    ARM Erratum 754322 affects Cortex-A9 revisions r2p* and r3p*.

    Automatically enable support code to mitigate the erratum when compiling
    a kernel for any of the affected Renesas SoCs:
    - RZ/A1: r3p0,
    - R-Mobile A1: r2p4,
    - R-Car M1A: r2p2-00rel0,
    - R-Car H1: r3p0,
    - SH-Mobile AG5: r2p2.

    EMMA Mobile EV2 (r1p3) and RZ/A2 (r4p1) are not affected.
