[U-Boot] USB mass storage gadget patch

[Lukasz Majewski <l.majewski@samsung.com>]

Hi victor,

Regarding UMS support:

The last version posted at u-boot ML can be found at [**]:
http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/113004/match=ums



I've go through your fixes for file_storage.c. 


Please find appended diff file [*] for changes which I was able to
apply on the original file_storage.c file (taken from [**]).

I've attached output from Host dmesg and target's console (output.txt)

It seems that on my setup your patches are causing errors and UMS is
not working (e.g. partitions aren't exported).

I don't have enough time now to delve to your solution, but I'm
skeptical about hard setting EPs (like below).

+if (fsg_fs_bulk_out_desc.bEndpointAddress != 0x1)
+	fsg_fs_bulk_out_desc.bEndpointAddress = 0x1;
+

If possible, please align to patch set [**], so we can have the same
setup.

However, I will try to find some time to help you with the problem
(that's why I've asked for description of the problem, which you are
trying to fix).
