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
|
2022-04-20 14:10:07 +00:00
|
|
|
property called 'u-boot,bootconf' in the '/chosen' node in device tree.
