+=== Configure U-Boot environment variables ===
+Documentation for configuration of u-boot-xlnx_%.bbappend, bsp.cfg, and platform-top.h can be found [https://www.xilinx.com/support/documentation/sw_manuals/xilinx2020_2/ug1144-petalinux-tools-reference-guide.pdf here] on page 99. Because u-boot autoconfig is being deprecated, this is the workaround to avoid the need for platform-auto.h.
