Subject: [PATCH 4/8] ARM: dts: aspeed: ampere: Declare SPI NOR flashes on boards
Date: Thu, 13 Aug 2026 19:22:29 +0900 [thread overview]
Message-ID: <20260813102233.3088939-5-jackyhuang@nvidia.com> (raw)
In-Reply-To: <20260813102233.3088939-1-jackyhuang@nvidia.com>
Declare jedec,spi-nor flash nodes with the properties previously
inherited from aspeed-g6.dtsi stubs. Keep status = "okay" so these
boards stay enabled while the SoC stubs still exist.
Signed-off-by: Jacky Huang <jackyhuang@nvidia.com>
