From e9faf9b0b07a317f6ac40ab67e5490a1c4df5fc6 Mon Sep 17 00:00:00 2001 From: Nicolas Saenz Julienne Date: Tue, 24 Jan 2023 12:02:13 +0100 Subject: ARM: add multi_v7_lpae_defconfig 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.
