Add a defconfig for ICnova A20 SomPi compute module on ADB4006 development board with Allwinner A20 chip and 512MB/1GB RAM. Board support package includes the following components: - mainline Linux kernel 6.1.35 - mainline U-Boot 2023.04 - custom dts & uboot defconfig - default packages from buildoot https://wiki.in-circuit.de/index.php5?title=ICnova_ADB4006 https://wiki.in-circuit.de/index.php5?title=ICnova_A20_SODIMM The Linux DTS is already accepted upstream and will be part of Linux 6.5: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/arm/boot/dts?id=de2bdfb7f79d5c655eb056d459e02be2c7f13c8b The U-Boot DTS and defconfig have been submitted: https://lists.denx.de/pipermail/u-boot/2023-May/518688.html Signed-off-by: Ludwig Kormann <ludwig.kormann@ict42.de> Tested-by: Kilian Zinnecker <kilian.zinnecker@mail.de> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
