There is no and never was a Kconfig for ARM_ERRATA_794072 in the kernel tree. So, there is no need to select ARM_ERRATA_794072 in ./arch/arm/mach-npcm/Kconfig. Simply drop selecting the non-existing ARM_ERRATA_794072. This issue was discovered with ./scripts/checkkconfigsymbols.py.

Doing some searching, u-boot had a workaround for something called ARM_ERRATA_794072. https://github.com/u-boot/u-boot/commit/f71cbfe3ca5d2ad20159871700e8e248c8818ba8 Lore has the review history for that patch: https://lore.kernel.org/all/6be32e0b5b454ed7b609317266a8e798@BLUPR03MB358.namprd03.prod.outlook.com/ (local) It looks like it's the same workaround as ARM_ERRATA_742230, which the kernel does implement. It would be good to hear from the Nuvoton people, or an Arm person.
