[PATCH 4/4] board: keymile: add support for seli8 design based on nxp ls102x soc

Aleksandar Gerasimovski
The SELI8 design is a new tdm service unit card for Hitachi-Powergrids
XMC and FOX product lines.

It is based on NXP LS1021 SoC and it provides following interfaces:
 - IFC interface for NOR, NAND and external FPGA's
 - 1 x RGMII ETH for debug purposes
 - 2 x SGMII ETH for management communication via back-plane
 - 1 x uQE HDLC for management communication via back-plane
 - 1 x I2C for peripheral devices
 - 1 x SPI for peripheral devices
 - 1 x UART for debug logging

It is foreseen that the design will be later re-used for another XMC and
FOX service cards with similar SoC requirements.

Please trim subject to 60 characters

>The SELI8 design is a new tdm service unit card for Hitachi-Powergrids XMC and
>FOX product lines.
>
>It is based on NXP LS1021 SoC and it provides following interfaces:
> - IFC interface for NOR, NAND and external FPGA's
> - 1 x RGMII ETH for debug purposes
> - 2 x SGMII ETH for management communication via back-plane
> - 1 x uQE HDLC for management communication via back-plane
> - 1 x I2C for peripheral devices
> - 1 x SPI for peripheral devices
> - 1 x UART for debug logging
>
>It is foreseen that the design will be later re-used for another XMC and FOX
>service cards with similar SoC requirements.
