-Subject: [PATCH] image-fdt: save name of FIT configuration in '/chosen' node
-
-It can be useful for the OS (Linux) to know which configuration has
-been chosen by U-Boot when launching a FIT image.
-Store the name of the FIT configuration node used in a new string
-property called 'u-boot,bootconf' in the '/chosen' node in device tree.
