Like many other projects, U-Boot has a tradition of including big
blocks of License headers in all files. This not only blows up the
source code with mostly redundant information, but also makes it very
difficult to generate License Clearing Reports. An additional problem
is that even the same lincenses are referred to by a number of
slightly varying text blocks (full, abbreviated, different
indentation, line wrapping and/or white space, with obsolete address
information, ...) which makes automatic processing a nightmare.
To make this easier, such license headers in the source files will be
replaced with a single line reference to Unique Lincense Identifiers
as defined by the Linux Foundation's SPDX project [1]. For example,
in a source file the full "GPL v2.0 or later" header text will be
replaced by a single line:
SPDX-License-Identifier: GPL-2.0+
We use the SPDX Unique Lincense Identifiers here; these are available
at [2].
Note: From the legal point of view, this patch is supposed to be only
a change to the textual representation of the license information,
but in no way any change to the actual license terms. With this patch
applied, all files will still be licensed under the same terms they
were before.
Note 2: The apparent difference between the old "COPYING" and the new
"Licenses/gpl-2.0.txt" only results from switching to the upstream
version of the license which is differently formatted; there are not
any actual changes to the content.
Note 3: There are some recurring questions about linense issues, such
as:
- Is a "All Rights Reserved" clause a problem in GPL code?
- Are files without any license header a problem?
- Do we need license headers at all?
The following excerpt from an e-mail by Daniel B. Ravicher should help

| It is not a conflict to grant a license and also reserve all rights, as
| implicit in that language is that you are reserving all "other" rights
| not granted in the license. Thus, a file with "Licensed under GPL, All

arm/km: fix u-boot update functionality
Due to the new I2C framework we need to adapt the u-boot update
function. Due to the new framework all i2c leafs behind a mux are
present in the system and not only those who are defined and used. So it
is bus number 5 after the rework.

i2c, multibus: get rid of CONFIG_I2C_MUX
CONFIG_I2C_MUX is replaced through the new i2c multibus/multiadapter
framework, configured through CONFIG_SYS_I2C. As CONFIG_I2C_MUX
is only used on the keymile boards, and they are now completely
moved to the new framework, remove CONFIG_I2C_MUX.
