From: Konstantin Porotchkin <kostap at marvell.com>

The Marvell reference platform CN9130-CRB is a small form factor
board in a metal case. The platform is based on CN9130 SoC with
addition of 8 Gigabit ports SOHO Ethernet switch.
The reference platform features the following:
* Up to 4 CPU cores ARMv8 Cortex-A72 CPU
* CPU core operating speed of up to 2.2GHz
* DDR4 DIMM – 8GB 64bit+ECC @ 2400Mhz.
* 1x eMMC 8GB device
* 1x uSD card 4 bits port on CP
* 1x 128MB SPI NOR flash memory
* 1x USB 3.0 Host port (Type A)
* 1x SATA Gen3 via M.2
* 1x USB 3.0 via M.2
* 1x SIM card slot
* 1x 1G Ethernet port via RGMII
* 1x 10G switch port over SFP+ connector
* 8x 1G ports through 88E6393X switch via XFI
* 1x 2.5G/1G/100M/10M port via HS_SGMII
* 1x PCI Express (PCIe)x1 Gen 3.0
* 1x PCI Express (PCIe)x4 Gen 3.0 via NVMe M.2
* JTAG port

The CRB board uses MCP23017 i2c pin controller that drives the
onboard eMMC abd USB 3,0 port power lines.
The following configuration should be enabled for this controller
support:
CONFIG_PINCTRL_MCP23S08=y

The plaform supports two HW configurations - "A" and "B"
CN9130-CRB-A
* AP-MPP configuration: SDIO, UART
* CP0 Serdes configuration:
	* Lane0-3: NVMe (PCIe x4)
	* Lane4: XFI
	* Lane5: HS_SGMII

2. CN9130-CRB-B
* AP-MPP configuration: SDIO, UART
* CP0-MPP configuration: RGMII, SDIO, I2C0, I2C1, SMI, XSMI
* CP0 Serdes configuration:
	* Lane0: PCIe x1
	* Lane1: USB3_0 x1
	* Lane2: SATA x1
	* Lane3: USB3_1 x1
	* Lane4: XFI
	* Lane5: HS_SGMII
