An unusual feature of the XArray is the ability to create entries which
occupy a range of indices. Once stored to, looking up any index in
the range will return the same entry as looking up any other index in
the range. Setting a mark on one index will set it on all of them.
Storing to any index will store to all of them. Multi-index entries can
be explicitly split into smaller entries, or storing ``NULL`` into any
entry will cause the XArray to forget about the range.

Search Marks
------------
Each entry in the array has three bits associated with it called marks.
Each mark may be set or cleared independently of the others. You can
iterate over marked entries by using the xa_for_each_marked() iterator.
You can enquire whether a mark is set on an entry by using
xa_get_mark(). If the entry is not ``NULL``, you can set a mark on it
by using xa_set_mark() and remove the mark from an entry by calling
xa_clear_mark(). You can ask whether any entry in the XArray has a
particular mark set by calling xa_marked(). Erasing an entry from the
XArray causes all marks associated with that entry to be cleared.
Setting or clearing a mark on any index of a multi-index entry will
affect all indices covered by that entry. Querying the mark on any
index will return the same result.
There is no way to iterate over entries which are not marked; the data
structure does not allow this to be implemented efficiently. There are
not currently iterators to search for logical combinations of bits (eg
iterate over all entries which have both ``XA_MARK_1`` and ``XA_MARK_2``
set, or iterate over all entries which have ``XA_MARK_0`` or ``XA_MARK_2``
set). It would be possible to add these if a user arises.

- fsl,erratum-a011043
Usage: optional
Value type: <boolean>
Definition: Indicates the presence of the A011043 erratum
describing that the MDIO_CFG[MDIO_RD_ER] bit may be falsely
set when reading internal PCS registers. MDIO reads to
internal PCS registers may result in having the
MDIO_CFG[MDIO_RD_ER] bit set, even when there is no error and
read data (MDIO_DATA[MDIO_DATA]) is correct.
Software may get false read error when reading internal
PCS registers through MDIO. As a workaround, all internal
MDIO accesses should ignore the MDIO_CFG[MDIO_RD_ER] bit.
For internal PHY device on internal mdio bus, a PHY node should be created.
See the definition of the PHY node in booting-without-of.txt for an
example of how to define a PHY (Internal PHY has no interrupt line).
