2ff5d641f2 drivers: entropy: mcux_trng: get the base address from the device tree
Instead of getting the base address from the MCUX headers, use the base
address from the device tree.

30e558f333 devices: entropy: Initialize drivers during PRE_KERNEL_1 stage
To ensure that early code that requires entropy has the HWRNG devices
fully initialized, initialize them all during PRE_KERNEL_1 stage.

8b883a61a3 subsys/random: sys_rand32_get() implementation that uses entropy API
Instead of every hardware number generator driver providing an
implementation of this function, use the random device API to
centralize the implementation of this function.

This is a very simplistic function that can be seen as a stepping stone
to refactor the random number generation in Zephyr.

da9b0ddf5b drivers: Rename random to entropy
This should clear up some of the confusion with random number
generators and drivers that obtain entropy from the hardware.  Also,
many hardware number generators have limited bandwidth, so it's natural
for their output to be only used for seeding a random number generator.
