Subject: [PATCH v2 15/22] Kconfig: sunxi: prepare for using drivers/ram/sunxi
Date: Thu, 28 Sep 2023 22:54:48 +0100 [thread overview]
Message-ID: <20230928215455.28094-16-andre.przywara@arm.com> (raw)
In-Reply-To: <20230928215455.28094-1-andre.przywara@arm.com>
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 make this entry
depend on that already.
