	Switch to using qcrypto_random_bytes() rather than rand() as our source of randomness for the BCM2835 RNG. If qcrypto_random_bytes() fails, we don't want to return the guest a non-random value in case they're really using it for cryptographic purposes, so the best we can do is a fatal error. This shouldn't happen unless something's broken, though. In theory we could implement this device's full FIFO and interrupt semantics and then just stop filling the FIFO. That's a lot of work, though, and doesn't really give a very nice diagnostic to the user since the guest will just seem to hang.

2017-02-28	target-arm: Implement BCM2835 hardware RNG	Marcin Chojnacki
	Recent vanilla Raspberry Pi kernels started to make use of the hardware random number generator in BCM2835 SoC. As a result, those kernels wouldn't work anymore under QEMU but rather just freeze during the boot process. This patch implements a trivial BCM2835 compatible RNG, and adds it as a peripheral to BCM2835 platform, which allows to boot a vanilla Raspberry Pi kernel under Qemu. Changes since v1: * Prevented guest from writing [31..20] bits in rng_status * Removed redundant minimum_version_id_old * Added field entries for the state * Changed realize function to reset Signed-off-by: Marcin Chojnacki <marcinch7@gmail.com> Message-id: 20170210210857.47893-1-marcinch7@gmail.com Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
