[Minios-devel] [UNIKRAFT PATCH v2 1/7] plat: build: Add a config option to enable fp on arm64

[Jia He <justin.he@xxxxxxx>]

This config is to enable the support for arm64 fp feature. Fp is for
application only, never for Unkraft kernel itself.

This config is 'n' by default since there is some overhead during context
switch.
