Looks like a recent change is not working for AARCH64
https://github.com/tianocore/edk2/commit/b5701a4c7a0fb185e0c5b9db9525939c78664bfd
edk2-platforms/Platform/ARM/JunoPkg/ArmJuno.dsc(...): error 4000:
Instance of library class [RngLib] is not found
in [/home/andrew/src/edk2/CryptoPkg/Library/OpensslLib/OpensslLib.inf]
[AARCH64]
consumed by module [/home/andrew/src/edk2/NetworkPkg/IScsiDxe/IScsiDxe.inf]
- Failed -
Build end time: 12:56:54, Sep.30 2020
Build total time: 00:00:01
Sorry but I have not found my way around here yet. Is there anyone that
can see what the best fix is for this please?
Thanks,
Andrew

Hi Andrew,
Welcome to the list.
First of all, it helps to cc maintainers of the bits you're having
issues with.
The GetMaintainer.py script can look these up for you automatically
for a given path:
python ../edk2/BaseTools/Scripts/GetMaintainer.py -l Platform/ARM/JunoPkg/ArmJuno.dsc
Platform/ARM/JunoPkg/ArmJuno.dsc
Leif Lindholm <leif@nuviainc.com>
Ard Biesheuvel <ard.biesheuvel@arm.com>
Thomas Abraham <thomas.abraham@arm.com>
Anyway, yes - commit b5701a4c7a0f ("CryptoPkg: OpensslLib: Use RngLib
to generate entropy in rand_pool"), merged through
https://github.com/tianocore/edk2/pull/938 broke EmulatorPkg, and most
platforms outside the main edk2 tree.
This should have been handled better.
But the fix is simple - if the platform port produces EFI_RNG_PROTOCOL
from some onboard hw, you can use the approach from edk2-platforms
commit 1e09147a01ae ("Platforms/RaspberryPi: Fix RPi4 RngLib build error").
Otherwise, you can use the approach used in edk2 commit 416813753726
("ArmVirtPkg: Add RngLib based on TimerLib for CryptoPkg").
If you're just trying to build something, you can rewind your edk2
HEAD to the edk2-stable202008 tag.
Best Regards,
Leif

Thank you. I did BIOS work and some UEFI in a previous role but have
been out of the loop for some years.

Thanks for the pointer, will do in future.

Just to be sure I understand this - most platforms outside of the main
edk2 tree are going to need updating to take account of this change.

Thanks, good to know.

Well, most non-x86 platforms. There is an RdRand implementation in
tree, which I expect most platforms that could use already did.

Emphasis on "onboard hw".
I find it incredibly attractive and good system design that
Silicon/Broadcom/Bcm283x/Drivers/Bcm2838RngDxe
can *exist*, because the underlying *platform hardware* also exists. I
wish we had something similar for virt, i.e. randomness available from
just a handful of fixed location MMIO registers. Randomness is needed
way earlier than when various bus enumerations occur, such as PCI, or
even virtio-mmio.
See also: why virtio-serial is unusable as a real debug output device.
Yes, I know, on Intel there's RDRAND and friends; they didn't have good
press, and it's still unclear to me how much one can count on RDRAND's
presence on the various QEMU/KVM CPU models.
