This is to cover machines which uses SPL to support multiple SoC
(Wandboard, CuBox-i, ...) and then has:

#@TYPE: Machine
#@NAME: Wandboard i.MX6 Wandboard Quad/Dual/Solo
#@SOC: i.MX6Q/DL
#@DESCRIPTION: Machine configuration for i.MX6 Wandboard Quad
#@MAINTAINER: Alfonso Tames <alfonso at tames.com>

MACHINEOVERRIDES =. "mx6:mx6dl:mx6q:"

which expands for:

% MACHINE=wandboard bitbake core-image-base -e | grep '^MACHINEOVERRIDES='
MACHINEOVERRIDES="armv7a:imx:mx6:imxpxp:imxipu:imxvpu:imxgpu2d:imxgpu3d:imxepdc:mx6dl:mx6q:wandboard"
