-/***********************************************************************
- *
- *	Theory of operation
- *
- * Note: in this description 'included' means that a node (or other part
- * of the tree) should be included in the region list, i.e. it will have
- * a region which covers its part of the tree.
- *
- * This function maintains some state from the last time it is called.
- * It checks the next part of the tree that it is supposed to look at
- * (p.nextoffset) to see if that should be included or not. When it
- * finds something to include, it sets info->start to its offset. This
- * marks the start of the region we want to include.
- *
- * Once info->start is set to the start (i.e. not -1), we continue
- * scanning until we find something that we don't want included. This
- * will be the end of a region. At this point we can close off the
- * region and add it to the list. So we do so, and reset info->start
- * to -1.
- *
- * One complication here is that we want to merge regions. So when we
- * come to add another region later, we may in fact merge it with the
- * previous one if one ends where the other starts.
- *
- * The function fdt_add_region() will return -1 if it fails to add the
- * region, because we already have a region ready to be returned, and
- * the new one cannot be merged in with it. In this case, we must return
- * the region we found, and wait for another call to this function.
- * When it comes, we will repeat the processing of the tag and again
- * try to add a region. This time it will succeed.
- *
- * The current state of the pointers (stack, offset, etc.) is maintained
- * in a ptrs member. At the start of every loop iteration we make a copy
- * of it.  The copy is then updated as the tag is processed. Only if we
- * get to the end of the loop iteration (and successfully call
- * fdt_add_region() if we need to) can we commit the changes we have
- * made to these pointers. For example, if we see an FDT_END_NODE tag,
- * we will decrement the depth value. But if we need to add a region
- * for this tag (let's say because the previous tag is included and this
- * FDT_END_NODE tag is not included) then we will only commit the result
- * if we were able to add the region. That allows us to retry again next
- * time.
- *
- * We keep track of a variable called 'want' which tells us what we want
- * to include when there is no specific information provided by the
- * h_include function for a particular property. This basically handles
- * the inclusion of properties which are pulled in by virtue of the node
- * they are in. So if you include a node, its properties are also
- * included.  In this case 'want' will be WANT_NODES_AND_PROPS. The
- * FDT_REG_DIRECT_SUBNODES feature also makes use of 'want'. While we
- * are inside the subnode, 'want' will be set to WANT_NODES_ONLY, so
- * that only the subnode's FDT_BEGIN_NODE and FDT_END_NODE tags will be
- * included, and properties will be skipped. If WANT_NOTHING is
- * selected, then we will just rely on what the h_include() function
- * tells us.
- *
- * Using 'want' we work out 'include', which tells us whether this
- * current tag should be included or not. As you can imagine, if the
- * value of 'include' changes, that means we are on a boundary between
- * nodes to include and nodes to exclude. At this point we either close
- * off a previous region and add it to the list, or mark the start of a
- * new region.
- *
- * Apart from the nodes, we have mem_rsvmap, the FDT_END tag and the
- * string list. Each of these dealt with as a whole (i.e. we create a
- * region for each if it is to be included). For mem_rsvmap we don't
- * allow it to merge with the first struct region. For the stringlist,
- * we don't allow it to merge with the last struct region (which
- * contains at minimum the FDT_END tag).
