Subject: [PATCH v4 1/2] arm64: dts: ti: k3-am64-main: Add GPMC memory controller node
Date: Tue,  2 Aug 2022 13:44:55 +0300	[thread overview]
Message-ID: <20220802104456.11069-2-rogerq@kernel.org> (raw)
In-Reply-To: <20220802104456.11069-1-rogerq@kernel.org>

The GPMC is a unified memory controller dedicated for interfacing
with external memory devices like
  - Asynchronous SRAM-like memories and ASICs
  - Asynchronous, synchronous, and page mode burst NOR flash
  - NAND flash
  - Pseudo-SRAM devices
