Low-level debug console UART
└─>Via ODMDATA
In linux kernel since version 3.1 (release Date: 2011-10-24)  
Automatically determines which UART to use for low-level debug based
on the ODMDATA value. This value is part of the BCT, and is written
to the boot memory device using nvflash, or other flashing tool.
When bits 19:18 are 3, then bits 17:15 indicate which UART to use;
0/1/2/3/4 are UART A/B/C/D/E.
