16*5986453bSStuart Yoder        Definition: The EREF (EREF: A Programmer.s Reference Manual for
17*5986453bSStuart Yoder	Freescale Power Architecture) defines the architecture for Freescale
18*5986453bSStuart Yoder	Power CPUs.  The EREF defines some architecture categories not defined
19*5986453bSStuart Yoder	by the Power ISA.  For these EREF-specific categories, the existence of
20*5986453bSStuart Yoder	a property named fsl,eref-[CAT], where [CAT] is the abbreviated category
21*5986453bSStuart Yoder	name with all uppercase letters converted to lowercase, indicates that
22*5986453bSStuart Yoder	the category is supported by the implementation.
