I am developing a device using the TQMLS102xA module by TQ. I am currently attempting to change the U-boot code to display some boot process LEDs (to aid in debugging). However, looking at the "arch/arm/include/asm/arch-ls102xa/gpio.h" file, the GPIO functionality has not been implemented for this device.
Why has the GPIO functionality not been implemented in U-boot for the LS102xA?
Is it likely to be implemented and/or can someone point me in the direction of some guidance on how I can implement this myself?
