The BeagleBone Black differs from the other AM335x boards in a few
significant ways, so it makes sense to create a custom configuration
for it. In particular, it uses eMMC instead of NAND flash.
Some boards, such as the BeagleBone Black, have an eMMC chip intstead
of NAND. We can use the eMMC boot partition to store the environment,
since it isn't used for anything else. This allows us to have a
configurable environment on those boards.
Many modern U-Boot ports enable command line editing and
a history buffer. The am335x_evm configuration is fairly
comprehensive as it is, so a few extra kb should not be
noticable, and it adds a very convenient feature.
accessing a lan9303 switch with the cpsw driver results in wrong
speed detection, as the switch sets the BMSR_ERCAP in BMSR
register, and follow read of the MII_STAT1000 register fails, as
the switch does not support it. Current code did not check,
if a phy_read() fails ... fix this.

NOR requires that s_init be within the first 4KiB of the image so that

environment in NOR at 512KiB and a redundant copy at 768KiB. We avoid

If no other bootoption works, try loading up device tree and zImage.
This is selected as the last option to allow backward compatibility as

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?

| It is not a conflict to grant a license and also reserve all rights, as

| 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

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

have such a horrible duplication of code.
Note that the mx23evk grew in size slightly. This is due to the

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.
