Subject: kernel/modules: add chaoskey module, hardware TRNG
X-Git-Tag: v19.07.0-rc1~3392
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=163ab9135a9148d510cd19ca90782835e8ca80bb;p=oweals%2Fopenwrt.git

kernel/modules: add chaoskey module, hardware TRNG

Package the driver for Chaoskey, a USB dongle that provides a
True Random Number Generator (TRNG) and feeds entropy to kernel.

Chaoskey driver is included the upstream Linux sources, so
only packaging it is needed.

Run-tested with ipq806x/R7800 and mvebu/WRT3200ACM.

(Requires CONFIG_HW_RANDOM kernel option.)
