However, this check does not happen until after earlycon is initialized, which means the work-around is not used, and the console hangs as soon as it displays one character. [Test Case] Enable earlycon and boot the kernel. Please see comments below for detailed test results on QDF2400 system. [Regression Potential] This impacts only Qualcomm Datacenter Technologies QDF2400 platforms.
