USB MASS STORAGE on SoCKit

FYI - for anyone else needing USB mass storage to work.

I thought "dr_mode" was "host" by default for backwards compatibility. I was wrong. It's needed (socfpga_cyclone_5_sockit.dts):

&usb1 {

status = "okay"

dr_mode = "host"

};

In addition, one other driver was needed:

- device drivers-> [*]usb support->[*] usb attached scsi

Some other options were not needed, leaving me with:

- Device Drivers-> [*]USB Support

- Device Drivers-> [*]USB Support->[*] Support for Host-side USB

- Device Drivers-> [*]USB Support->[*] USB Announce new devices

- Device Drivers-> [*]USB Support->[*] EHCI HCD (USB2.0) support

- Device Drivers-> [*]USB Support->[*] EHCI HCD (USB2.0) support->[*] Root Hub Transaction Translators

- Device Drivers-> [*]USB Support->[*] EHCI HCD (USB2.0) support->[*] Improved Transaction Translator scheduling

- Device Drivers-> [*]USB Support->[*] USB Mass Storage support

- Device Drivers-> [*]USB Support->[*] DesignWare USB2 DRD Core Support (Host only mode)

- Device Drivers-> [*]USB Support->[*] USB Physical Layer Drivers

- Device Drivers-> [*]USB Support->[*] USB Physical Layer Drivers->[*] NOP USB Transceiver Driver

- Device Drivers-> [*] SCSI Device Support

- Device Drivers-> [*] legacy /proc/scsi/ support

- Device Drivers-> [*] SCSI disk support

With these options in place fdisk sees the USB stick and partitions on it can be mounted.

Have fun!
