From 8bddb9742bedaffacf5cd0dfdaa443079a216ca9 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Sun, 18 Dec 2022 00:12:07 +0000 Subject: [PATCH] Kconfig: sunxi: prepare for using drivers/ram/sunxi At the moment all Allwinner DRAM initialisation routines are stored in arch/arm/mach-sunxi, even though those "drivers" are just a giant collection of writel's, without any architectural dependency. The R528/T113-s SoC (with ARM cores) and the D1/D1s Soc (with RISC-V cores) share the same die, so should share the same DRAM init routines as well. To prepare for this, add a new sunxi directory inside drivers/ram, and add some stub entries to prepare for the addition of the share DRAM code for those SoCs. The RISC-V D1(s) SoCs will probably use SPL_DM, so for that SoC this would be the right directory anyway.
