Subject: [PATCH] hwrng: cavium - HW_RANDOM_CAVIUM should depend on ARCH_THUNDER
Git-commit: ab7d88549e2f7ae116afd303f32e1950cb790a1d
Patch-mainline: v5.18-rc1
References: git-fixes
The Cavium ThunderX Random Number Generator is only present on Cavium
ThunderX SoCs, and not available as an independent PCIe endpoint. Hence
add a dependency on ARCH_THUNDER, to prevent asking the user about this
driver when configuring a kernel without Cavium Thunder SoC support.
Fixes: cc2f1908c6b8f625 ("hwrng: cavium - Add Cavium HWRNG driver for ThunderX SoC.")
