[redhat] New configs in drivers/char

Jeremy Cline requested to merge configs/2020-06-02/drivers/char into os-build

Hi,

As part of the ongoing rebase effort, the following configuration options need to be reviewed.

As a reminder, the ARK configuration flow involves moving unreviewed configuration options from the pending directory to the ark directory. In the diff below, options are removed from the pending directory and added to the ark hierarchy. The final options that need to be ACKed are the files that are being added to the ark hierarchy.

If the value for a file that is added should be changed, please reply with a better option.

CONFIG_HW_RANDOM_CCTRNG:

Say 'Y' to enable the True Random Number Generator driver for the Arm TrustZone CryptoCell family of processors. Currently the CryptoCell 713 and 703 are supported. The driver is supported only in SoC where Trusted Execution Environment is not used. Choose 'M' to compile this driver as a module. The module will be called cctrng. If unsure, say 'N'.

Symbol: HW_RANDOM_CCTRNG [=n] Type : tristate Defined at drivers/char/hw_random/Kconfig:477 Prompt: Arm CryptoCell True Random Number Generator support Depends on: HW_RANDOM [=y] && HAS_IOMEM [=y] && OF [=y] Location: -> Device Drivers -> Character devices -> Hardware Random Number Generator Core support (HW_RANDOM [=y])
