Marvell/Drivers: XenonDxe: Use new enums for SD card initialization

[edk2-devel] [edk2-platforms: PATCH] Marvell/Drivers: XenonDxe: Use new enums for SD card initialization

Posted by Marcin Wojtas 4 years, 7 months ago

MdeModulePkg/SdMmcHcDxe update to use rev 3 of SdMmcOverrideProtocol
reworked SD card initialization and added new enums describing lower
speeds. Include this in XenonDxe, which fixes Armada70x0Db SD interface.
