Disabling PM (and even avoiding WFI using 'nohlt') will not fix this problem, since it's related to the idle-mode of the IP block itself. What fixes the problem is the series from Santosh for the SYSC removal. Santosh, it seems that series combined a fix for this problem with some cleanup of the hwmod code that Paul had some concerns with. Is there any chance you can split up that series into a fix targetted at the DT-boot UART problem and a feature cleanup for hwmod? Then we hopefully get this fix into v3.10-rc and work on the hwmod changes/cleanup for the following merge window.
