From ad7f6bc2e1163125cdb26f6b0e6695554028626a Mon Sep 17 00:00:00 2001 From: Star Zeng Date: Thu, 26 Nov 2015 08:52:12 +0000 Subject: [PATCH] ArmVirtPkg: Use SerialDxe in MdeModulePkg instead of EmbeddedPkg Beyond just changing the directly related lines in the FDF and DSC files, we have to adapt the EarlyFdtPL011SerialPortLib and FdtPL011SerialPortLib instances as well, in the same patch. This is because the EmbeddedPkg driver expects the SerialPortSetAttributes(), SerialPortSetControl() and SerialPortGetControl() functions from SerialPortExtLib, while the MdeModulePkg driver expects them from SerialPortLib itself. We cannot implement these functions in ArmVirtPkg's SerialPortLib instances *before* flipping the driver, because it would cause double function definitions in the EmbeddedPkg driver. We also can't implement the functions *after* flipping the driver, because it would cause unresolved function references in the MdeModulePkg driver. Therefore we have to implement the functions simultaneously with the driver replacement.
