Re: [PATCH v2 1/3] ARM: dts: rockchip: Add support for phyCORE-RK3288 SoM
From: Jacob Chen

Hi wadim,
2017-04-06 21:04 GMT+08:00 Wadim Egorov <w.egorov@xxxxxxxxx>:
> The phyCORE-RK3288 is a SoM (System on Module) containing a RK3288 SoC.
> The module can be connected to different carrier boards.
> It can be also equipped with different RAM, SPI flash and eMMC variants.
> The Rapid Development Kit option is using the following setup:
>
> - 1 GB DDR3 RAM (2 Banks)
> - 1x 4 KB EEPROM
> - DP83867 Gigabit Ethernet PHY
> - 16 MB SPI Flash
> - 4 GB eMMC Flash
