[edk2-devel] [PATCH 0/1] EDK2 Serial driver UART debug print enablement

["Borzeszkowski, Alan" <alan.borzeszkowski@intel.com>]

On Intel platforms, we use LPSS UART for debug prints in DXE phase. Current implementation involves using custom driver.
In order to reduce code maintenance cost and flash usage, we want to switch to EDK2 Serial driver.
To achieve that, we need to load Serial driver shortly after DXE Core is invoked. Otherwise, this driver
will load at BDS which omits the purpose of debug prints in DXE. Separate .inf file is created
to introduce minimal changes to current implementation.
Change was tested on Intel platform, debug prints appeared shortly after DXE phase begun and console
redirection works.
