Subject: [PATCH] random: Drop ARCH limitations for CONFIG_RANDOM_TRUST_CPU
Date: Sun, 29 Mar 2020 10:29:09 +0200 [thread overview]
Message-ID: <20200329082909.193910-1-alexander.sverdlin@gmail.com> (raw)
The option itself looks attractive for the embedded devices which often
have HWRNG but less entropy from user-input. And these devices are often
ARM/ARM64 or MIPS. The reason to limit it to X86/S390/PPC is not obvious.
