Justin Hibbits b14959dacc random: Add PowerPC 'darn' instruction entropy source
Summary:
PowerISA 3.0 adds a 'darn' instruction to "deliver a random number".  This
driver was modeled after (rather, copied and gutted of) the Ivy Bridge
rdrand driver.

This uses the "Conditional Random Number" behavior to remove input bias.

From the ISA reference the 'darn' instruction, and the random number
generator backing it, conforms to the NIST SP800-90B and SP800-90C
standards, compliant to the extent possible at the time the hardware was
designed, and guarantees a minimum 0.5 bits of entropy per bit returned.
