Subject: [PATCH v3 3/3] riscv: Enable CONFIG_OF_BOARD_FIXUP by default for OF_SEPARATE
Date: Thu, 25 Jun 2020 00:37:26 -0700	[thread overview]
Message-ID: <1593070646-6774-3-git-send-email-bmeng.cn@gmail.com> (raw)
In-Reply-To: <1593070646-6774-1-git-send-email-bmeng.cn@gmail.com>

From: Bin Meng <bin.meng@windriver.com>

Starting from OpenSBI v0.7, the SBI firmware inserts/fixes up the
reserved memory node for PMP protected memory regions. All RISC-V
boards needs to copy the reserved memory node from the device tree
provided by the firmware to the device tree used by U-Boot.

Turn on CONFIG_OF_BOARD_FIXUP by default for OF_SEPARATE.

Signed-off-by: Bin Meng <bin.meng@windriver.com>

Changes in v3:
- change to "default y if OF_SEPARATE"
