Setting gpio pins in uboot (colibri imx8x)

I have an requirement where I must set the following pins as GPIO inputs in uboot on the colibri-imx8x module.

<IMX8QXP_QSPI0B_DATA3_LSIO_GPIO3_IO21		0x04000060>,		/* SODIMM  98 */

 <IMX8QXP_QSPI0A_DQS_LSIO_GPIO3_IO13		    0x04000060>,		/* SODIMM  73 */

 <IMX8QXP_CSI_RESET_LSIO_GPIO3_IO03			0x04000060>,		/* SODIMM  29 */

Can you please advise how I would do this in uboot ?

You can do it using U_boot gpio command.
Please note that after Linux boots, the GPIO properties will be redefined according to the Device Tree settings.
