Subject: [PATCH v2 10/10] ARM: add multi_v7_lpae_defconfig
Date: Fri, 20 Jan 2023 14:34:55 +0100 [thread overview]
Message-ID: <20230120133455.3962413-11-alexander.stein@ew.tq-group.com> (raw)
In-Reply-To: <20230120133455.3962413-1-alexander.stein@ew.tq-group.com>
From: Nicolas Saenz Julienne <nsaenzjulienne@suse.de>
The only missing configuration option preventing us from using
multi_v7_defconfig with the Raspberry Pi 4 is ARM_LPAE. It's needed as
the PCIe controller found on the SoC depends on 64bit addressing, yet
can't be included as not all v7 boards support LPAE.
Introduce multi_v7_lpae_defconfig, built off multi_v7_defconfig, which will
avoid us having to duplicate and maintain multiple similar configurations.
Needless to say the Raspberry Pi 4 is not the only platform that can
benefit from this new configuration.
