Hi Judith,

Sorry for late.

Reusing the uniphier-efuse driver seems reasonable to me.

The driver is already fairly generic, and contains no arch-specific elements
that would justify introducing a dedicated driver at this point.

Provided the functionality has been validated on the target hardware,
I would prefer to reuse the driver rather than write another similar driver.

Thank you,
