When creating an entry, check for an expanded version of that entry, then
use it instead. This allows, for example use of:
u-boot {
};
instead of having to write out in full:
u-boot {
type = "section";
u-boot-nodtb {
};
u-boot-dtb {
};
};
Add an implementaion of this and associated documentation.

This is a section containing the U-Boot binary, BSS padding if needed and a
|
|
devicetree. Using this entry type automatically creates this section, with
|
|
the following entries in it:
|
|
|
|
u-boot-spl-nodtb
|
|
u-boot-spl-bss-pad
|
|
u-boot-dtb
|
|
|
|
Having the devicetree separate allows binman to update it in the final
|
|
image, so that the entries positions are provided to the running U-Boot.
|
|
|
|
This entry is selected based on the value of the 'spl-dtb' entryarg. If
|
|
this is non-empty (and not 'n' or '0') then this expanded entry is selected.
