+    """A section which contains multiple entries
+
+    A section represents a collection of entries. There must be one or more
+    sections in an image. Sections are used to group entries together.
+
+    Attributes:
+        _node: Node object that contains the section definition in device tree
+        _size: Section size in bytes, or None if not known yet
+        _align_size: Section size alignment, or None
+        _pad_before: Number of bytes before the first entry starts. This
+            effectively changes the place where entry position 0 starts
+        _pad_after: Number of bytes after the last entry ends. The last
+            entry will finish on or before this boundary
+        _pad_byte: Byte to use to pad the section where there is no entry
+        _sort: True if entries should be sorted by position, False if they
+            must be in-order in the device tree description
+        _skip_at_start: Number of bytes before the first entry starts. These
+            effectively adjust the starting position of entries. For example,
+            if _pad_before is 16, then the first entry would start at 16.
+            An entry with pos = 20 would in fact be written at position 4
+            in the image file.
+        _end_4gb: Indicates that the section ends at the 4GB boundary. This is
+            used for x86 images, which want to use positions such that a
+             memory address (like 0xff800000) is the first entry position.
+             This causes _skip_at_start to be set to the starting memory
+             address.
