I am working on booting our Overo Fire board as fast as possible from cold
Is there anything like test pads on Overo Fire to modify sys_boot bits to
optimize the boot sequence?
The problem is sys_boot[0:5] seems to be 0b101111 by default on the board,
meaning it polls boot devices in this order:
USB -> UART3 -> MMC1 -> NAND
This results in ~0.5sec delay before seeing the first message "Texas
Instruments X-Loader 1.5.1" from X-Loader.
I would like to change the bits to 0b000110 to poll MMC1 first as we only
use a SD card.
