As per the description in boot sequence, ROM code in the processor will try multiple boot methods in particular sequence for a given sys_boot[]5:0] sequence.
Eg: for the sequence 001100, the boot preference order is NAND-EMAC-USB-MMC1
My question is, how does the ROM bootloader decide if that Boot mode is not usable and moves to next boot option.
In the above case, if fresh NAND (empty) present on board, on what Basis the boot loader moves to next boot option.
