SecurityPkg/RngDxe: Conditionally install EFI_RNG_PROTOCOL
|
|
|
|
On Arm platforms, the number of available RNG algorithms is
|
|
dynamically detected and can be 0 in the absence of FEAT_RNG
|
|
and firmware TRNG.
|
|
In this case, the EFI_RNG_PROTOCOL should not be installed to
|
|
prevent from installing an empty protocol.
