@ Make an educated guess regarding the memory map:
@ - the original A9 core tile, which has MPCore peripherals
@ located at 0x1e000000, should use UART at 0x10009000
@ - the original A9 core tile (based on ARM Cortex-A9 r0p1)
@ should use UART at 0x10009000
@ - all other (RS1 complaint) tiles use UART mapped
@ at 0x1c090000
