The data passed to mkimage is collected from subnodes of the mkimage node,
|
|
|
|
e.g.:
|
|
|
|
|
|
|
|
mkimage {
|
|
|
|
args = "-n test -T imximage";
|
|
|
|
|
|
|
|
u-boot-spl {
|
|
|
|
};
|
|
|
|
};
|
|
|
|
|
|
|
|
This calls mkimage to create an imximage with u-boot-spl.bin as the input
|
|
|
|
file. The output from mkimage then becomes part of the image produced by
|
|
|
|
binman.
