[PATCH 0/2][eoan] Support Ryzen 3rd gen (3900X) ECC

[Alex Hung]

BugLink: https://bugs.launchpad.net/bugs/1869235

[Impact]

ECC RAM is not supported for some families of AMD Ryzen 3rd gen CPUs in
kernel 5.3

[Fix]

Supports are added in kernel 5.4. The actual fix is e53a3b267f but
3e443eb353 contains the required PCI IDs.

[Test]

Verified on ASRockRack X470D4U2-2T as discussion on LP:1869235

[Regression Potential]

Low. They are cherry-picked from upstream kernel which has them since
kernel 5.4.
