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

barebox_update_handler_exists() to use the former function instead.

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

fs: improve ramfs_truncate speed ...

During sequential writes into single file, fs layer is consequently
calling ramfs_truncate() function. When file size grows
ramfs_truncate() takes more and more time to complete, due to
interations through all already written data chunks. As an example
loading ~450M image using usb fastboot protocol took over 500s to
complete.

Use ramfs_find_chunk() function to search for last chunk of data in
ramfs_truncate() implementation, which saves a lot of loop
iterations. As a result loading ~450M image using usb fastboot
protocol takes around 25s now.

arm: crypto: fix SHA256 shipped assembler code ...

Binutils 2.29 changed behavior of the adr instruction to always
add the thumb mode switch offset, which breaks usages where the
user is interested in the address of an internal symbol, instead
of a jump address. Binutils 3.31 fixed this by only adding the
offset when interworking is required.

As there are toolchains out there with broken binutils, it's better
to fix the code to work around the issue by not using the named
label.

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.

fs: ramfs: make chunk counting in truncate() better readable ...

In ramfs_truncate() "newchunks" denotes the number of chunks we
want to have after the call. We decrease that number while iterating
over the existing chunks and decrease it further with every newly
allocated chunk until "newchunks" is zero.
This is a bit hard to read. Instead we drop the decreasing while
iterating over existing chunks and increase "oldchunks" while allocating
until it reaches "newchunks".

This is mainly done to make the next patch easier.
