[edk2-devel] [PATCH 2/2] MdeModulePkg/AtaAtapiPassThru: Add support for drives in RAID mode

[Vitaly Cheptsov]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3118

This resolves the problem of using drivers connected to Intel G33
builtin SATA controller when run from DuetPkg when it can only
be configured in RAID mode through the firmware settings.
