Subject: [RFC PATCH v2 10/11] riscv: soc: Add Allwinner SoC kconfig option
Date: Sun,  6 Jun 2021 09:04:08 +0000	[thread overview]
Message-ID: <1622970249-50770-14-git-send-email-guoren@kernel.org> (raw)
In-Reply-To: <1622970249-50770-1-git-send-email-guoren@kernel.org>

From: Guo Ren <guoren@linux.alibaba.com>

Add Allwinner kconfig option which selects SoC specific and common
drivers that is required for this SoC.

Allwinner D1 uses custom PTE attributes to solve non-coherency SOC
interconnect issues for dma synchronization, so we set the default
value when SOC_SUNXI selected.
