[PATCH 0/2] Initial LS1021-IOT board support

[Renaud Barbier]

The LS1021A-IOT is NXP ARMv7 Layerscape evaluation board.

These patches provide a basic board support with:
	- UART
	- boot from SPI
	- One Ethernet port - eth1*

The content of the EEPROM having been lost so the MAC should be set in the
config file

The code is ported from NXP U-boot 2021-04. Like U-boot, the machine support
i.e mac-lxxx lives in its own directory. However, it is very similar to the 
ls1046a machine support. This migth be merged. Please advise.
