[U-Boot] [PATCH] A20-OLinuXino-Lime2: Enable USB gadget support

[U-Boot] [PATCH] A20-OLinuXino-Lime2: Enable USB gadget support

[Tom Rini]

Based on A13-OLinuXino, enable DFU and UMS support.

Signed-off-by: Tom Rini <trini@konsulko.com>

With this change I've added DFU to my tests on this board, and assuming a
follow up test with the SD image that kicks the board into FEL works, I'll
then enable the UMS tests on this board (and add DFU to SD, not just DFU to
RAM).

Do you need CMD_USB_MASS_STORAGE for your tests ? Enabling
CMD_USB_MASS_STORAGE really seems orthogonal to enabling GADGET
mode to me, esp. since it is only useful in host mode AFAICT.

Chen-Yu did something similar in a patch enabling host mode for a
different sunxi board and here is what I replied:

"
If we want to enable CONFIG_CMD_USB_MASS_STORAGE on sunxi, we really
should do so on all boards (feel free to submit a patch for this).

e.g. add something like this to board/sunxi/Kconfig:

config CMD_USB_MASS_STORAGE
     default y

So that we can still disable it in case there are space constraints,
but normally we enable it on all sunxi boards offering a
consistent set of available commands.
"

The same goes for this patch, otherwise this patch is:

Ig you want to feel free to apply this directly
(given that I've send out a sunxi pull-req recently).

Hans

Ah, no, things have bad names perhaps.  CMD_USB_MASS_STORAGE enables
"ums" as a command which is what in turn will export MMC (or something
else) as a USB mass storage gadget over to the host.

I think it's a useful command that should be more widely exposed, yes.
IIRC, it's how the Tegra platforms support flashing their dev boards
with official images, and can be a handy "rescue" type option too.

OK, thanks.  I just might since I really want to move on to grabbing
some fs patches and before I do that I really want to have as much
testing of them as possible.

Ah, I thought this enabled the (destructive) low level usb mass storage
block read/write test commands, but I guess I'm wrong.

I wonder why Chen-Yu put it in the usb host enabling patch for
an A33 board then...

Given the above, that should probably be:

config CMD_USB_MASS_STORAGE
        default y if USB_GADGET


Hmm, I guess we may want to have a bunch of those, so that
simply adding:

CONFIG_USB_MUSB_GADGET=y

To a defconfig enables the relevant related options...

Hans

Yes.  I think that something that should be done, and sooner rather than
later, is changing more options from 'default n' (the default when not
spelled out) to 'default y' as with the change from board.h to Kconfig
there is much less pain in turning off default values.  Things like
'ums' are really handy and unlike DFU/fastboot don't require additional
configuration.  So, I should go and fire off a patch for this one
quickly at least.

It was copy pasted from some other defconfig. Like you, I thought it was
for host mode supporting USB sticks...
