From 193279d784e2ca2225815803b9a63f1ce3c7389d Mon Sep 17 00:00:00 2001 From: Andrei Gherzan Date: Wed, 24 Jul 2019 15:39:04 +0100 Subject: [PATCH] RPI: Add defconfigs for rpi4 (32/64) This defines a minimum defconfig for each of the two Raspberry Pi 4 variants. One notable difference is that we don't have a embedded dt for this board given that the fw supplies us with one which we can reuse. Furthermore, the ram size is not queryable through mbox interface as the maximum reported size is 1G. The fw patches the dt with the right memory configuration and uboot uses it as it is. We avoid u-boot touching this configuration by making sure CONFIG_ARCH_FIXUP_FDT_MEMORY is deactivated.
