hwrng: histb - Move driver to drivers/char/hw_random/histb-rng.c

2023-05-12T10:48:01+00:00

Move to drivers/char/hw_random since histb-(t)rng does not provide
cryptography pseudo rng.

histb-rng is pretty like hisi-rng, but after investigation, we confirm
there is no RNG_PHY_SEED register on histb-rng so a separate driver is
needed.

Still we rename relevant function names to match those in hisi-rng.

hwrng: mpfs - add polarfire soc hwrng support

2022-04-15T08:34:28+00:00

Add a driver to access the hardware random number generator on the
Polarfire SoC. The hwrng can only be accessed via the system controller,
so use the mailbox interface the system controller exposes to access the
hwrng.

hwrng: Add Arm SMCCC TRNG based driver

2021-08-06T11:45:26+00:00

The "Arm True Random Number Generator Firmware Interface"[1] provides
an SMCCC based interface to a true hardware random number generator.
So far we are using that in arch_get_random_seed(), but it might be
useful to expose the entropy through the /dev/hwrng device as well. This
allows to assess the quality of the implementation, by using "rngtest"
from the rng-tools package, for example.

Add a simple platform driver implementing the hw_random interface.
The corresponding platform device is created by the SMCCC core code,
we just match it here by name and provide a module alias.

Since the firmware takes care about serialisation, this can happily
coexist with the arch_get_random_seed() bits.

hwrng: hisi - remove HiSilicon TRNG driver

2020-11-27T06:13:42+00:00

Driver of HiSilicon true random number generator(TRNG)
is removed from 'drivers/char/hw_random'.

Both 'Kunpeng 920' and 'Kunpeng 930' chips have TRNG,
however, PRNG is only supported by 'Kunpeng 930'.
So, this driver is moved to 'drivers/crypto/hisilicon/trng/'
in the next to enable the two's TRNG better.
