From 4ed209326b5299584ad22b82d0f5ba0d12ceb169 Mon Sep 17 00:00:00 2001 From: Chuanhong Guo Date: Thu, 8 Aug 2024 12:56:03 +0800 Subject: [PATCH] siflower: new target for Siflower SF19A2890 Siflower SF19A2890 is an SoC with: Dual-core MIPS InterAptiv at 800MHz DDR3 controller One Gigabit Ethernet MAC with RGMII and IPv4 HNAT engine Built-in 2x2 11N + 2x2 11AC WiFi radio USB 2.0 OTG I2C/SPI/GPIO and various other peripherals This PR adds support for SF19A2890 EVB with ethernet support. EVB spec: Memory: DDR3 128M Ethernet: RTL8367RB 5-port gigabit switch Flash: 16M NOR Others: MicroUSB OTG, LED x 1, Reset button x1 The built image can be flashed using u-boot recovery. This target is marked as source-only until support for a commercial router board comes.

GINTSTS + +The DWC OTG 3.30a found on Siflower SF19A2890 has battery charger +support enabled. It triggers MultVallpChng interrupt (bit 20 of +GOTGINT) but doesn't set OTGInt in GINTSTS.
