Binman currently supports updating the main device tree with things like the position of each entry. Extend this support to SPL and TPL as well, since they may need (a subset of) this information. Also adjust DTB output files to have a .out extension since this seems clearer than having a .dtb extension with 'out' in the name somwhere. Also add a few missing comments and update the DT setup code to use ReadFile and WriteFile(). Signed-off-by: Simon Glass <sjg@chromium.org>

Properties / Entry arguments: (see binman README for more information)
|
|
- size: Size of section in bytes
|
|
- align-size: Align size to a particular power of two
|
|
- pad-before: Add padding before the entry
|
|
- pad-after: Add padding after the entry
|
|
- pad-byte: Pad byte to use when padding
|
|
- sort-by-offset: Reorder the entries by offset
|
|
- end-at-4gb: Used to build an x86 ROM which ends at 4GB (2^32)
|
|
- name-prefix: Adds a prefix to the name of every entry in the section
|
|
when writing out the map

A section is an entry which can contain other entries, thus allowing

hierarchical images to be created. See 'Sections and hierarchical images'
