76116f29ee highbank: enable keyed autoboot stop
Restrict autoboot interruption to "s" or "d" keys. This will prevent some
unwanted stopping and also allow disabling the reset on command timeout.

0f7cf3803f ARM: highbank: avoid bss write in timer_init
The timer_init function is called before relocation and writes to bss data
were corrupting relocation data. Fix this by removing the call to
reset_timer_masked. The initial timer count should be 0 or near 0 anyway,
so initializing the variables are not needed.

eca3aeb352 Licenses: introduce SPDX Unique Lincense Identifiers
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
with these:

|
| 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
| Rights Reserved" would mean that it is licensed under the GPL, but no
| other rights are given to copy, modify or redistribute it.

5434caf5ba ARM: mxs: Consolidate configuration options
Pull all the duplicate configuration options into configs/mxs.h
from the board configuration files. This reduces the files greatly
and makes them somewhat more readable. Besides, we do no longer
have such a horrible duplication of code.

Note that the mx23evk grew in size slightly. This is due to the
CONFIG_SYS_CBSIZE now being set to 1024 as it is on the rest of
MXS systems.

This patch also fixes the OCRAM size for i.MX23. The i.MX23 has
only 32kB of OCRAM, while i.MX28 has 128kB of OCRAM.

I verified the configuration didn't change for each of the boards,
but I didn't boot-test it on the boards I do not have. I configured
U-Boot for each board using the "make ... <board>_config" command
and then ran "cpp -I include -dM include/config.h" , which dumped
all the configuration options. I did this both before and after this
patch and finally compared the results for each MXS board. Actually,
the results do differ slightly, since the configs/mxs.h file now
properly includes the correct iomux-mx23.h or iomux-mx28.h , so
while comparing, I had to ignore these new defines. These have no
impact on U-Boot configuration though.

The timer3 counter unit for lastdesc and now values are inconsistent in current
code. The unit of "readl(&tmr->timer3_counter) / (CONFIG_SYS_CLK_FREQ / 2)" is
second. However, CONFIG_SYS_HZ is defined as 1000 in board config file.
This means the accuracy of "lastdec" and "now" should be in millisecond,
thus fix the equation to set lastdec and now variables accordingly.
