Both <conf> and <subimg> are unit names from the image source file (dts
format) used to generate the image. For example, having an image
generated using the source file with the following structure:
/{
images {
[EMAIL PROTECTED] { ...
[EMAIL PROTECTED] { ...
[EMAIL PROTECTED] { ...
[EMAIL PROTECTED] { ...
[EMAIL PROTECTED] { ...
[EMAIL PROTECTED] { ...
};
configurations {
[EMAIL PROTECTED] { ...
};
};
one could in U-Boot do:
bootm 300000:[EMAIL PROTECTED]
bootm 300000:[EMAIL PROTECTED] :[EMAIL PROTECTED] :[EMAIL PROTECTED]
bootm 300000:[EMAIL PROTECTED] - 300000:[EMAIL PROTECTED]
bootm 300000:[EMAIL PROTECTED]
This will be documented better in the form of a doc/README.<something>
file that we plan to post. And I'd rather not add too much documentation
to the commit log, especially now that Wolfgang has merged the patches
to the new-image branch of u-boot-testing.
