  96           Automatically determines which UART to use for low-level debug based
  97           on the ODMDATA value. This value is part of the BCT, and is written
  98           to the boot memory device using nvflash, or other flashing tool.
  99           When bits 19:18 are 3, then bits 17:15 indicate which UART to use;
 100           0/1/2/3/4 are UART A/B/C/D/E.

 105           Automatically determines which UART to use for low-level debug based
 106           on the UART scratch register value. Some bootloaders put ASCII 'D'
 107           in this register when they initialize their own console UART output.
 108           Using this option allows the kernel to automatically pick the same
 109           UART.
