 ADL, Iris, Azalea, Lotus, Marigold have support in hardware but the BIOS does not expose it to the OS.
 
+Some platforms have it enabled in BIOS and exposed through ACPI to the OS,
+meaning no detailed configuration is necessary, just telling the OS to use e.g.
+`ttyS0`. Other platforms, e.g. Sunflower, need custom configuration to tell the
+OS about the memory map offset.

 ### BIOS
 
 The BIOS settings can be managed through the CPU UART console by enabling
