-
-PCI BAR 5 is not setup correctly for the on-board AHCI
-controller on Broadcom's Vulcan processor. Added a quirk to fix BAR 5
-by using BAR 4's resources which are populated correctly but NOT used
-by the AHCI controller actually.
-
-RHEL-only:
-
-Both patches are in RHEL-7.6 also. Inclusion of the patches into RHEL-8
-was discussed. Since there are partners with Ax system configurations it
-was decided to carry them in RHEL8 too. See:
