BOOTING PROCEDURE
Preliminary Spec 0.51
14.1 External Boot
It support an external boot ROM.
When external boot mode, the sequence begins from external ROM that is attached to nCS3.
The bus width of external boot ROM can be determined by state of GPIO_A[5:4] at the rising
edge of nRESET pin. If GPIO_A[5:4] == 0, the bus width is 16bit, if GPIO_A[5:4] == 1, it is 8bit,
otherwise, it is 32bit. (Refer to the chapter of memory controller for more details)
