usb: gadget: fastboot: terminate commands with NULL

2014-10-06T19:07:44+00:00

Without NULL termination, various commands will read past the
end of input. In particular, this was noticed with error()
calls in cb_getvar and simple_strtoul() in cb_download.

Since the download callback happens elsewhere, the 4k buffer
should always be sufficient to handle command arguments.

usb: musb-new: core: set MUSB_POWER_HSENAB in MUSB_POWER for host mode

2014-10-06T19:04:44+00:00

This bit allows the MUSB controller to negotiate for high-speed mode when
the device is reset by the hub. If unset, Babble errors occur with
high-speed mass storage devices right after the first packet. This condition
is not caught by the interrupt handles in U-Boot, so no recovery is done,
and the USB communication is stuck.

To fix this, set the bit unconditionally, not only for
CONFIG_USB_GADGET_DUALSPEED but also for host-only modes.

usb: tegra: ULPI regression on tegra20

2014-10-06T14:12:48+00:00

Trying to enumerate USB devices connected via ULPI to T20 failed as
follows:

USB2:   ULPI integrity check failed

Git bisecting revealed the following commit being at odds:

commit 2d34151f7501ddaa599897f0d89ad576126b03eb
usb: tegra: refactor PHY type selection

Looking at above commit one quickly identifies a copy paste error which
this patch fixes. Happy ULPIing again (;-p).

usb: gadget: fastboot: explicitly set radix of maximum download size

2014-10-06T12:50:44+00:00

The processing of the max-download-size variable requires a
radix specifier, or the fastboot host tool will interpret
it as an octal number.

usb: gadget: fastboot: add max-download-size variable

2014-10-06T12:50:44+00:00

Current Android Fastboot seems to use 'max-download-size' instead
of 'downloadsize' variable to indicate the maximum size of sparse
segments.

usb: ci_udc: respect CONFIG_USB_GADGET_DUALSPEED

2014-10-06T12:50:44+00:00

Force full-speed (12 Mbit/s) operation if CONFIG_USB_GADGET_DUALSPEED
is not defined.

The controller is capable of high-speed (480 Mbit/s) operation,
but some designs may require the use of lower-speed operation.

usb: gadget: fastboot: improve download progress bar

2014-10-06T12:50:43+00:00

When download is ongoing, if the actual size of one transfer
is not the same as BYTES_PER_DOT, which will cause the dot
won't print anymore. Then it will let the user thinking it
is stuck, actually it is transfering without dot printed.

So, improve the method to show the progress bar (print dot).

usb: f_mass_storage: set removable flag in do_inquiry based on LUN

2014-10-06T12:50:43+00:00

Without this flag, tools like Alex Page's USB Image Tool
won't see drives exposed over USB Gadget as removable,
and won't allow access to them.
