- 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.
