Subject: [PATCH/RFC v2] ARM: shmobile: defconfig: Enable LPAE
Date: Wed, 25 Apr 2018 17:14:35 +0100	[thread overview]
Message-ID: <1524672875-14130-1-git-send-email-fabrizio.castro@bp.renesas.com> (raw)

On iWave's iwg20m DDR1 512MB memory cannot be accessed with 32-bit
addresses, hence we need LPAE.
