I would like to connect a FPGA to the ELBC of P4080, and then access the FPGA from Linux BSP via P4080 ELBC.
There some simple questions against the configurations under UBOOT. Could you please share if there any experience? Any comments would be appreciated.
1, how to configure the GPCM Mode for the ELBC of P4080
2, how to configure the OR/BR register (for example OR4, BR4)
3, how to configure the CS (for example CS4, CS5)
4, are there any more registers which I need to configure?
