The commit 5dd95cf93dfffa1d19a1928990852aac9f55b9d9 'usb_storage:
Fix EHCI "out of buffer pointers" with CD-ROM' introduce a bug in
usb_storage as it wrongly assumes that every transfer can use
4096 bytes per qt_buffer. This is wrong if the start address of
the data is not page aligned to 4096 bytes and leads to 'EHCI
timed out on TD' messages because of 'out of buffer pointers'
in ehci_td_buffer function.
The bug appears during load of a fragmented file and
read from or write to an unaligned memory address.

I applied this and pushed into u-boot-usb. Thanks again for finding and fixing
this.
I'm still uncertain if we should add it into current release so late, probably
not though. Therefore I'll queue it for next, ok?
Given that there was nobody other than me with the problem until now, it
should be okay.
Regards,
Stefan
