> Subject: [PATCH] config/arm: support crypto in cortex-a78ae mcpu
>
> ARM cortex-a78ae configuration (part number 0xd42) is being built without the
> necessary crypto extensions. This results in infinite loops in the crypto
> performance tests applications because the hardware crypto features are not
> properly enabled.
> This fix enables the crypto extension in the mcpu definition.
>
> Fixes: c02c01dbf907 ("config/arm: prefer strict use of -mcpu if supported")
