[PATCH 00/12] hw_random: add 6 more RNG drivers

[Ahmad Fatoum]

While stack protector support can be used without HWRNG, it will
print a warning about the fixed canary to alert to the fact that it
requires a random canary to be able to withstand an attacker.

Linux HWRNG drivers are surprisingly easy to port to barebox though,
so let's import 6 for commonly used platforms.

Notably missing is the CAAM for i.MX8M, which will follow separately.

Ahmad Fatoum (12):
  hw_random: support ctrlc()
  ARM: io: read 32 bits at once for aligned I/O memcpy/memset
  driver: implement dev_platform_get_and_ioremap_resource
  hw_random: add struct hwrng::priv member
  hw_random: remove confusing left-overs from kernel help texts
  hw_random: remove reference to undefined CONFIG_HW_RANDOM
  hw_random: add Atmel RNG driver
  hw_random: add BCM2835 RNG driver
  hw_random: add IPROC RNG200 driver for BCM2711
  hw_random: add Rockchip RNG support
  hw_random: add timeriomem_rng driver
  hw_random: add OMAP RNG driver
