[PATCH 0/4] bootconfig: Add mixed subkeys and value under the same key

[Masami Hiramatsu]

Hi,

The following series updates bootconfig to support mixed subkeys and
a value under the same key. Since the kernel cmdline accepts options
like "aaa.bbb=val1 aaa.bbb.ccc=val2", it is better that the bootconfig
also support it.

This series depends on the previous bugfix which I sent last week;

 https://lore.kernel.org/lkml/162087519356.442660.11385099982318160180.stgit@devnote2/

With this series, sub-keys and a value can co-exist under a parent key.
For example, following config is allowed.

 foo = value1
 foo.bar = value2

Note, since there is no syntax to add raw value in the structured
key, you have to define it outside of the brace. For example

 foo.bar = value1
 foo.bar {
         baz = value2
         qux = value3
 }

Also, the order of the value node under a key is fixed. If there
are a value and subkeys, the value is always the first child node
of the key. Thus if user specifies subkeys first, e.g.

 foo.bar = value1
 foo = value2

In the program (and /proc/bootconfig), it will be shown as below

 foo = value2
 foo.bar = value1


Thank you,
