Commit 41a9ada3 ("of/fdt: mark hotpluggable memory") introduced
two (for systems with and without memblock) weak versions of
early_init_dt_mark_hotplug_memory_arch(), that could be overridden by an
architecture-specific version.  However, no overrides ever emerged.
Later, commit aca52c39 ("mm: remove CONFIG_HAVE_MEMBLOCK")
removed the non-memblock version.

Allow to extend expression of sub nodes to optionally indicate bit
position. This extension is needed to distinguish between different bit
positions in the same address.

For example, there are two nvmem nodes starting with bit 4 and bit 0
at the same address 0x54. In this case, it can be expressed as follows.

    trim@54,4 {
        reg = <0x54 1>;
        bits = <4 2>;
    };
    trim@54,0 {

While unflattening the device tree, we try to populate dt nodes and
properties into tree-shaped data structure.

In populate_properties function, pprev is initially set to
&np->properties, and then updated to &pp->next.

In both scenarios *pprev is NULL, since the memory area that we are
allocating from is initially zeroed.

I tested the code as below, and it showed that BUG was never called.

-       if (!dryrun)
+       if (!dryrun) {
+               if (*pprev)
