This is really a loooong delay, there any specific reason for such a long
delay, I'm seeing this to slow down the boot up significantly?

Otherwise looks OK to me, and I prefer the defconfig file change to
be a separate patch please.

Actually, This is just an example for other real products. There is no
such spi_reset pin on Aspenite , so machine info set it spi_gpio_reset
= -1. Or do you think we should delete these lines?
