[PATCH 0/2] virtio: rng: Handle oversized return buffers

[Kavin Gunasekara]

On Arm FVP platforms the virtio backend sometimes returns more bytes
than requested. The virtio spec does not forbid returning extra
bytes. U-Boot’s existing virtio-rng test treats such cases as errors
and the test checks if an error is returned, leading to test failures
on FVPs.

To prevent the test failing in such cases, U-Boot should properly
handle such cases. Patch 1 adjusts the test, while patch 2 relaxes
the error check in the rng code.
