libfdt: Add helper function to create a trivial, empty tree
The libfdt read/write functions are now usable enough that it's become a
moderately common pattern to use them to build and manipulate a device
tree from scratch. For example, we do so ourself in our rw_tree1 testcase,
and qemu is starting to use this model when building device trees for some
targets such as e500.
However, the read/write functions require some sort of valid tree to begin
with, so this necessitates either having a trivial canned dtb to begin with
or, more commonly, creating an empty tree using the serial-write functions
first.
This patch adds a helper function which uses the serial-write functions to
create a trivial, empty but complete and valid tree in a supplied buffer,
ready for manipulation with the read/write functions.

dfu: mmc: file buffer: remove static allocation
For writing files, DFU implementation requires the file buffer
with the len at least of file size. For big files it requires
the same big buffer.
Previously the file buffer was allocated as a static variable,
so it was a part of U-Boot .bss section. For 32MiB len of buffer
we have 32MiB of additional space, required for this section.
The .bss needs to be cleared after the relocation.
This introduces an additional boot delay at every start, but usually
the dfu feature is not required at the standard boot, so the buffer
should be allocated only if required.
This patch removes the static allocation of this buffer,
and alloc it with memalign after first call of function:
- dfu_fill_entity_mmc()
and the buffer is freed on dfu_free_entity() call.
This was tested on Trats2.
A quick test with trace. Boot time from start to main_loop() entry:
- ~888ms - before this change (arch memset enabled for .bss clear)
- ~464ms - after this change

This change is possible since those gadgets now must take care to allocate
buffers aligned to cache line (CONFIG_SYS_CACHELINE_SIZE).
This can be achieved by using DEFINE_CACHE_ALIGN_BUFFER() or
ALLOC_CACHE_ALIGN_BUFFER() macros. Those take care to allocate buffer
aligned to cache line in both starting address and its size.
Sometimes it is enough to just use memalign() with size being a
multiplication of cache line size.

simply when trying to write a FAT/ext file that is larger than the buffer
dfu_mmc.c maintains for this purpose.
Signal the error by switching the DFU state/status. This will be picked
up by the DFU client when it sends the next DFU request. Note that errors
can't simply be returned from e.g. dnload_request_complete(), since that
function has no way to pass errors back to the DFU client; a call to
dnload_request_complete() simply means that a USB OUT completed.
This error state/status needs to be cleared when the next DFU client
connects. While there is a DFU_CLRSTATUS request, no DFU client seems to
send this. Hence, clear this when selecting the USB alternate setting on
the USB interface.
Finally, dfu.c relies on a call to dfu_flush() to clear up the internal
state of the write transaction. Now that errors in dfu_write() are
detected, dfu_flush() may no longer be called for every transaction.

dfu: fix some issues with reads/uploads
DFU read support appears to rely upon dfu->read_medium() updating the
passed-by-reference len parameter to indicate the remaining size
available for reading.
dfu_read_medium_mmc() never does this, and the implementation of
dfu_read_medium_nand() will only work if called just once; it hard-codes
the value to the total size of the NAND device irrespective of read
offset.
I believe that overloading dfu->read_medium() is confusing. As such,
this patch introduces a new function dfu->get_medium_size() which can
be used to explicitly find out the medium size, and nothing else.
dfu_read() is modified to use this function to set the initial value for
dfu->r_left, rather than attempting to use the side-effects of
dfu->read_medium() for this purpose.
Due to this change, dfu_read() must initially set dfu->b_left to 0, since
no data has been read.
dfu_read_buffer_fill() must also be modified not to adjust dfu->r_left
when simply copying data from dfu->i_buf_start to the upload request
buffer. r_left represents the amount of data left to be read from HW.
That value is not affected by the memcpy(), but only by calls to
dfu->read_medium().
After this change, I can read from either a 4MB or 1.5MB chunk of a 4MB
eMMC boot partion with CONFIG_SYS_DFU_DATA_BUF_SIZE==1MB. Without this
change, attempting to do that would result in DFU read returning no data

with zero's when reused. While at it, make checkpatch happy.

dfu: Disable default calculation of CRC32
Patch (SHA1:
bd694244db7bc969954)
dfu: Introduction of the "dfu_hash_algo" env variable for checksum method
setting
already introduced more generic handling of the crc32 calculation.
Up till now the CRC32 of received data was calculated unconditionally.
This patch changes this and from now - by default the crc32 is NOT
calculated anymore.

dfu: Introduction of the "dfu_hash_algo" env variable for checksum method setting
Up till now the CRC32 of received data was calculated unconditionally.
The standard crc32 implementation causes long delay when large images
were uploaded.
The "dfu_hash_algo" environment variable gives the opportunity to
disable on demand the hash (crc32) calculation.
It can be done without the need to recompile the u-boot binary.
By default the crc32 is calculated, which means that legacy behavior
has been preserved.
Tests results:
400 MiB ums.img file
With crc32 calculation: 65 sec [avg 6.29 MB/s]
Without crc32 calculation: 25 sec [avg 16.17 MB/s]

dfu: mmc: Provide support for eMMC boot partition access
Before this patch it was only possible to access the default eMMC HW
partition. By partition selection I mean the access to eMMC via the
ext_csd[179] register programming.
It sometimes happens that it is necessary to write to other partitions.
This patch adds extra attribute to "raw" sub type of the dfu_alt_info
environment variable (e.g. boot-mmc.bin raw 0x0 0x200 mmcpart 1;)
It saves the original boot value and restores it after storing the file.

drivers:dfu: dfu_flush(): add raw data flush to complete dfu write
Before dfu write and flush operations separation,
dfu write data was flushed by host download request
with len of zero size.
Since above change manually calling dfu write with zero
size has non sense (e.g. in THOR). This should be done by
flush operation.
So now dfu_write_buffer_drain() is called in dfu_flush().
If there is any raw data to flush (like it can be in thor)
then it will be physically written to medium.

USB: gadget: save driver name before registering it
g_dnl_register() currently first attempts to register a composite
driver by name, and then saves the driver name once it's registered.
Internally to the registration code, g_dnl_do_config() is called and
attempts to compare the composite device's name with the list of known
device names. This fails since the composite device's name has not yet
been stored. This means that the first time "ums 0 0" is run, it fails,
but subsequent attempts succeed.
Re-order the name-saving and registration code to solve this.
