I don't know your hardware, nor do I know the Renesas rsk7203 board. I
have no idea how your board's reset sequence looks like, nor how the
Renesas board loads and starts U-Boot.

U-Boot can be configured in a plethora of different ways to fit all
sorts of hardware.

If your board differs from the Renesas board, you will have to port
U-Boot to your hardware. As only you know the hardware, and as it is
you who defines things like memory map etc., only you can decide how
to do that. The Renesas board may, or may not, be a good starting
point. I cannot comment on this.

Best regards,

Wolfgang Denk
