28 @ Make an educated guess regarding the memory map:
Pawel Moll852663d2012-09-04 17:06:20 +0100[diff] [blame]29 @ - the original A9 core tile (based on ARM Cortex-A9 r0p1)
30 @ should use UART at 0x10009000
Pawel Moll6a371952011-12-09 18:47:39 +0000[diff] [blame]31 @ - all other (RS1 complaint) tiles use UART mapped
32 @ at 0x1c090000
