Date: Tue, 9 May 2023 21:01:25 +0100 Message-Id: <20230509200125.309026-1-liviu@dudau.co.uk> X-Mailer: git-send-email 2.40.0 MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-mips@vger.kernel.org This WiFi AP is based on a MT7621 SoC with 128MiB RAM, 128MiB NAND, a MT7603 2.4GHz WiFi and a MT7663 5GHz WiFi chips integrated on the board, connected to the main SoC over PCIe. The GMAC1 on the SoC is connected to PHY0 on the GSW and can be used to improve routing bandwidth. The device uses NMBM over NAND, which is not currently supported in the mainline, so NAND node is skipped in this revision.
