Title: Uboot support USB host
hi,

Due to the USB command didn't listed when I type "help" in rkboot.
I would like to know if the USB host driver is OK or not.
Because I want to use fatload in rkboot to do something.

Thanks.

It shuld be here: u-boot/drivers/usb/host/

I am new to firefly. I found that rockchip didn't use the normal driver architecture.
For example, mmc driver is not in u-boot/drivers/mmc but board/rockchip/common/emmc/
So, I want to know if the real usb host driver is in u-boot/drivers/usb/host...or in other place.

@zhansb Do you have experiment of usb host driver on the rockchip platform?

Best& regards

For example, ...

you're right. Rockchip doesn't use standard driver interface
