Title:
tty: pl011: fix earlycon work-around for QDF2400 erratum 44
Status in linux package in Ubuntu:
Incomplete
Bug description:
[Impact]
The work-around for the Qualcomm Datacenter Technologies QDF2400 erratum 44
sets the qdf2400_e44_present" global variable if the work-around is needed.
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.
[Regression Potential]
This impacts only Qualcomm Datacenter Technologies QDF2400 platforms.
[Fix]
