of: unflatten: access property properly ...

Properties have to be accessed with of_property_get_value() rather than
accessing them directly from the devicenode. The accessor does the
right thing when of_new_property_const() is used.

mtd: do not attach already attached UBI ...

in mtd_detect we do not check if the mtd is already attached to UBI. If
it is we get the error:

ERROR: ubi: mtd0 is already attached to ubi0

Check before trying to attach it to avoid this message.

bbu: Add "handler" parameter to barebox_update() ...

Add "handler" parameter to barebox_update() and remove the code that
was respondible for header lookup before. With this change finding
appropriate handler is caller's responsibility, which makes it
possible to implement custom handler lookup/existence check, chache
it, and then re-use it without calling handler_find_by_* functions for
the second time.

Expose bbu_find_handler_by_device() and bbu_find_handler_by_name() as

With this done, barebox_update_handler_exists() is no longer used
anywhere in the code and can be removed.

usb: gadget: fastboot: fix downloading files of wMaxPacketSize bytes ...

File transfers with sizes of exact multiples of wMaxPacketSize up to
EP_BUFFER_SIZE do not work. For a typical scenario that would be files
of 512, 1024 ... 3584 bytes.

This happens because we unconditionally put EP_BUFFER_SIZE into the
initial request length. For non wMaxPacketSize aligned lengths this
works well because the transfer is completed with a short packet.
For wMaxPacketSize aligned lengths there is no short packet though,
so the transfer never completes. Instead we have to put the file
size into the initial request length.

Some controllers like the DWC3 do not work when the request length is
not aligned to wMaxPacketSize, so we align up to wMaxPacketSize like
done in U-Boot.
