[PATCH v3 0/2] Initial LS1021-IOT board support

[Renaud Barbier]

After the acceptance of the architected timer, the LS1021A support is sent
again as two patches.

The LS1021A-IOT is NXP ARMv7 Layerscape evaluation board.

These patches provide a basic board support with:
	- DDR3
	- UART
	- boot from SPI

The code is ported from NXP U-boot 2021-04.

Renaud Barbier (2):
  ARM: add LS1021A to Layerscape machine support
  ARM: Layerscape: Add LS1021A IOT board support
