The bmp command already has a way to centre the image. Using this CONFIG
option to also centre it makes it impossible to control where images are

By default several types of splash locations are supported and the
user can select one of them through environment var (splashsource).
However the devpart is still hardcoded and we cannot change it from
the environment.
This patch add the support of "splashdevpart" which allow the user to
set the devpart though this environment variable.
Example: image located in splashscreen partition (MMC as raw)
```
splashsource=mmc_raw
splashdevpart=0#splashscreen
```

At present these are attached to vidconsole which means that the video

The colours are a reasonable way of indexing common colours in any case,
so move them to the video uclass instead.

There are two problems with both strcmp and strncmp:
(1) The C standard is clear that the contents should be compared as
"unsigned char":
The sign of a nonzero value returned by the comparison functions
memcmp, strcmp, and strncmp is determined by the sign of the
difference between the values of the first pair of characters (both
interpreted as unsigned char) that differ in the objects being
compared.
(2) The difference between two char (or unsigned char) values can
range from -255 to +255; so that's (due to integer promotion) the
range of values we could get in the *cs-*ct expressions, but when that
is then shoe-horned into an 8-bit quantity the sign may of course
change.
The impact is somewhat limited by the way these functions
are used in practice:
- Most of the time, one is only interested in equality (or for
strncmp, "starts with"), and the existing functions do correctly
return 0 if and only if the strings are equal [for strncmp, up to
the given bound].
- Also most of the time, the strings being compared only consist of
ASCII characters, i.e. have values in the range [0, 127], and in
that case it doesn't matter if they are interpreted as signed or
unsigned char, and the possible difference range is bounded to
[-127, 127] which does fit the signed char.
For size, one could implement strcmp() in terms of strncmp() - just
make it "return strncmp(a, b, (size_t)-1);". However, performance of
strcmp() does matter somewhat, since it is used all over when parsing
and matching DT nodes and properties, so let's find some other place
to save those ~30 bytes.

- Reduce memory usage in SPL in some cases, clarify some standalone API
license issues, fix a Kconfig dependency, pin to a specific version of
python setuptools for now, fix a signing problem in mkimage and add a
memory uclass.
The GPMC is a unified memory controller dedicated for interfacing
with external memory devices like
- Asynchronous SRAM-like memories and ASICs
- Asynchronous, synchronous, and page mode burst NOR flash
- NAND flash
- Pseudo-SRAM devices
This driver will take care of setting up the GPMC based on
the settings specified in the Device tree and then
probe its children.

GPMC stands for General Purpose Memory Controller and it is
present on many Texas Instruments SoCs.
It supports a number of Asynchronous and Synchronous interfaces
and has various settings to configure the bus interface.
The DT bindings define all the various GPMC settings.
As the GPMC supports multiple devices on the bus, each
device is represented as a child and the respective
GPMC settings are situated there. (see ti,gpmc-child.yaml)
These binding docs are picked up from the Linux kernel.

On 2010-01-27, an email [1] was sent to the mailing list by Wolfgang
Denk which clarified the intended licensing exceptions for standalone
applications. As the "export.h" header and the "stubs.c" source files
are required to implement a standalone application, the intention was
that these files be covered by the licensing exception. This is made
clear in the following quotes from that email:
"exports.h" should be added to the "allowed" file list; there should
be no need to include "common.h". Eventually this needs fixing.
Patches are welcome.
"examples/standalone/stubs.c" should be added to the "allowed" file
list (the ppc_*jmp.S files are LGPLed).
There should be no doubts - the intention is clear, the current state
may need improvement. Help (read: patches) welcome.
