+Using multiconfig to build ZU+
+------------------------------
+
+multiconfig dependency has to be added in image file or local.conf.
+For example in core-image-minimal you will need
+do_image[mcdepends] = "multiconfig:zcu102:pmu:pmu-firmware:do_deploy"
+
+Add conf/multiconfig in the build directory and create pmu.conf and zcu102.conf
+
+Add the following in pmu.conf:
+ MACHINE="zynqmp-pmu"
+ DISTRO="xilinx-standalone"
+ GCCVERSION="7.%"
+ TMPDIR="${TOPDIR}/pmutmp"
+
+Add the following in zcu102.conf:
+ MACHINE="zcu102-zynqmp"
+ DISTRO="poky"
+
+In local.conf multiconfig is enabled by: BBMULTICONFIG ?= "zcu102 pmu"
+
+bitbake multiconfig:zcu102:core-image-minimal
+
+More information about multiconfig:
+https://www.yoctoproject.org/docs/current/mega-manual/mega-manual.html#dev-building-images-for-multiple-targets-using-multiple-configurations
+
+Workaround:
+There is additional workaround required in u-boot-xlnx recipe. Add the below dependency
+do_compile[mcdepends] = "multiconfig:zcu102:pmu:pmu-firmware:do_deploy"
