[U-Boot] USB mass storage gadget patch

[victor <victor@keyasic.com>]

Lukasz,

I am looking at the usb mass storage gadget patch from you at:
http://patchwork.ozlabs.org/patch/104516/

I am trying to use this patch in the u-boot. Some questions:
1) Is this patch in U-boot git release?
2) Now I can use the patch and process till SCSI MODE_SELECT_6 command, and
then problem is encountered. Basically the SCSI MODE_SELECT_6 is sent to EP1
Out, then data is sent to EP1 out, and the fsg_main_thread only sees the
data. I change the code to force the CSW.

The changes are:
1) fix the buf pointer in scsi inquiry
2) fix the buf pointer in scsi read format capacities
3) fix the buf pointer in CSW sending
4) fix attention condition checking in scsi command check
5) fix the context pointer before queue a request to read bulk only CBW
6) change bulk out endpoint from endpoint 2 to endpoint 1 to accommodate
gen2 usb hardware limitation
7) in pad_with_zeros(), comment out the bh->inreq->length = nsend
8) in received_cbw(), force to send CSW if CBW is invalid. Otherwise, the
IRQ routine keeps on reading the same data.

I attach the file for your reference. Please kindly advise me. Thanks.

Thanks,
victor
