Specification:
- Siflower SF21H8898
- 512MB DDR3, 128MB SPI-NAND and 16MB SPI-NOR
- 5x Gigabit ports (SF23P1240 QSGMII PHY and SF23P1211F RGMII PHY)
- 1x 2.5G port (Airoha EN8811H PHY)
- M.2 Key B slot with USB2.0, PCIEx1 and a NanoSIM card slot
- MiniPCIe slot with USB2.0 and PCIEx1
- 1x USB2.0 port through USB Hub
- PCF8563-compatible RTC
The SoC can only boot from SPI0. Two SPI flash chipselects are connected
to GPIO5 (SPI0 CS) and GPIO36 through a 2x2 jumper. It boots from
SPI-NOR or SPI-NAND depending on how the jumpers are connected.
The firmware can be flashed using U-boot web recovery from Siflower
vendor U-boot.

The same GPIO controller is found on all current Siflower SoCs,
with different number of GPIOs. Add ngpios property instead of
specifying it with dt match data.

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.
