Add the response string as a parameter to fastboot_okay/fail, instead
of modifying a global, to match the contract expected by the AOSP
U-Boot code.

write_sparse_image could be useful for non-fastboot users.
For ex a platform, without usb-device/fastboot support, could
get sparse images over tftp and write using the mmc command.
Or non-android systems could also leverage the sparse format.
Towards that, this patch removes anything fastboot specific from
the write_sparse_image implementation. Which includes making the
function return integer as error code and calls for fastboot logging
via an optional callback function 'mssg'.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

In order to process the CHUNK_TYPE_DONT_CARE properly, there is
a requirement to be able to 'reserve' a specified number of blocks
in the storage media. Because of the special handling of "bad blocks"
in NAND devices, this is implemented in a storage abstraction function.

- update fastboot_okay() and fastboot_fail()
This file originally came from upstream code.
While retaining the storage abstraction feature, this is the second

aboot.c

This "session-id" alogrithm is not required, and currently corrupts
the stored image whenever more the one "session" is required.

The Android sparse image format is currently supported through a file
called aboot, which isn't really such a great name, since the sparse image
format is only used for transferring data with fastboot.
Rename the file and header to a file called "sparse", which also makes it
consistent with the header defining the image structures.

The fastboot flash command that writes an image to a partition works in
several steps:
1 - Retrieve the maximum size the device can download through the
"max-download-size" variable
2 - Retrieve the partition type through the "partition-type:%s" variable,
that indicates whether or not the partition needs to be erased (even
though the fastboot client has minimal support for that)
3a - If the image is smaller than what the device can handle, send the image
and flash it.
3b - If the image is larger than what the device can handle, create a
sparse image, and split it in several chunks that would fit. Send the
chunk, flash it, repeat until we have no more data to send.
However, in the 3b case, the subsequent transfers have no particular
identifiers, the protocol just assumes that you would resume the writes
where you left it.
While doing so works well, it also means that flashing two subsequent
images on the same partition (for example because the user made a mistake)
would not work withouth flashing another partition or rebooting the board,
which is not really intuitive.
Since we have always the same pattern, we can however maintain a counter
that will be reset every time the client will retrieve max-download-size,
and incremented after each buffer will be flashed, that will allow us to
tell whether we should simply resume the flashing where we were, or start
back at the beginning of the partition.

The current sparse image parser relies heavily on the MMC layer, and
doesn't allow any other kind of storage medium to be used.
Rework the parser to support any kind of storage medium, as long as there
is an implementation for it.
