Subject: [PATCH V2 0/2] ARM: Layerscape: Add LS1021A IOT board support

[Renaud Barbier]

This is the version 2 of the LS1021A patches. It merges the machine support
into the Layerscape machine and add minimal support for UART, DDR3 and SPI
boot.
Unlike version 1, the network support is not present and will be provided
in another patch.

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