Replace existing hw_ranndom/exynos-rng driver with a new, reworked one.
This is a driver for pseudo random number generator block which on
Exynos4 chipsets must be seeded with some value. On newer Exynos5420
chipsets it might seed itself from true random number generator block
but this is not
Hi,
This is a follow up of my questions around exynos-rng [1].
Changes since v3:
=
1. New patch: 1/2 for ALIGN_DOWN macro. The change in metag architecture
was not compiled. Please test it.
2. Dropped patches touching ARM defconfig as they are not changing and
they pollute
Few parts of kernel define their own macro for aligning down so provide
a common define for this, with the same usage and assumptions as existing
ALIGN.
Convert also three existing implementations to this one.
