It has been tested on trimslice and also using the new iotrace feature. The implementation uses a top-level GPIO device (which has no actual GPIOS). Under this all the banks are created as separate GPIO devices. The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7, ..., Z0..Z7, AA0..AA7, etc. Since driver model is not yet available before relocation, or in SPL, a special function is provided for seaboard's SPL code.
