The A388-GP is a board produced by Marvell that holds
- 1 PCIe slot
- 2 mini PCIe slot (one of them is multiplexed with the PCIe slot,
muxing is selected through the GPIO expander)
- 1 16MB SPI-NOR
- 2 Gigabit Ethernet ports
- 4 SATA ports (2 of them are multiplexed with the mini PCIe slots,
muxing is selected through the GPIO expander)
- 1 SDIO slot
- 1 USB3 port
- 2 USB2 port
- 2 GPIO/interrupts expander on I2C

Hi Andrew,
I made a mistake and the file was improperly named
armada-385-gp.dts. This patch is the correct version.
Sorry for this.
