Matching anything that just happens to have the sought-for label as a
prefix is wrong. For example, if the board designer has designated 10
lines for debug purposes, named "debug1" through "debug10", and we are
looking up "debug1", if debug10 happens to be met first during the
iteration we'd wrongly return that.
In theory, this can break existing users that could rely on this
quirk, but OTOH keeping the current broken semantics can cause a lot
of grief for people hitting this in the future and not understanding
why they don't find the line they expect. Considering how few in-tree
defconfigs currently set DM_GPIO_LOOKUP_LABEL (ignoring sandbox, only
four "real" boards), let's fix it before the use becomes more
widespread.

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.

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.

OMAP3 BeagleBoard NAND boot hangs when spl_load_legacy_img() tries
to read the header into 'struct hdr' which is allocated on the
stack.
As the header has already been read once before by spl_nand.c,
we can avoid the extra header allocation and read here by
simply passing around the pointer to the header.

If a regulator does not support .set_suspend_enable or
.set_suspend_value then ret is set to ENOSYS early in the function.
The most serious impact of this is that when no automatic setting of
voltage is needed then the final regulator_set_enable() is skipped
because ret has not been cleared.
It seems that the error handling for regulator_set_suspend_value() is
also wrong as if this succeeds then the normal boot-on checks are still
required, and again ENOSYS needs special treatment here.

Currently the 'sf update' command fails in case the 'start' offset is
not aligned to SPI NOR erase block size. Add the missing alignment
calculation. In case the start offset is in the middle of erase block,
round start address down to the nearest aligned one, compare only the
updated data between what is in the SPI NOR and what is being written,
copy new data at offset of the compare buffer, and write back the entire
erase block.
This is useful e.g. on i.MX6Q where the u-boot-with-spl.imx is at
offset 0x400 in the SPI NOR, while the SPI NOR may have erase block
size e.g. 0x1000 bytes.
