A defconfig for the nanopi_neo4 was added ind1cd9cdf26, but then removed in8af7b11bd8because an ARM32 compiler was needed to build ATF, and this was not supported back then. Thanks to the addition of package/arm-gnu-a-toolchain/, we can now re-introduce this defconfig. Compared to the previous defconfig, the following changes were done: - enable BR2_TARGET_ARM_TRUSTED_FIRMWARE_NEEDS_ARM32_TOOLCHAIN - bump kernel to 5.4 - increase default rootfs size to 70M - use mainline u-boot - switch to Marek Belisko as maintainer Signed-off-by: Marek Belisko <marek.belisko@open-nandra.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
