The current macro is a misnomer since it does not declare a device
directly. Instead, it declares driver_info record which U-Boot uses at
runtime to create a device.
The distinction seems somewhat minor most of the time, but is becomes
quite confusing when we actually want to declare a device, with
of-platdata. We are left trying to distinguish between a device which
isn't actually device, and a device that is (perhaps an 'instance'?)
It seems better to rename this macro to describe what it actually is. The
macros is not widely used, since boards should use devicetree to declare
devices.
Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is
declaring a new driver_info record, not a device.

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private

GE B1x5v2 patient monitor series is similar to the CARESCAPE Monitor
series (GE Bx50). It consists of a carrier PCB used in combination
with a Congatec QMX6 SoM. This adds U-Boot support using device model
everywhere and SPL for memory initialization.
Proper configuration is provided as 'ge_b1x5v2_defconfig' and the
combined image u-boot-with-spi.imx can be flashed directly to 1024
byte offset to /dev/mtdblock0. Alternatively SPL and u-boot.imx can
be loaded separately via USB-OTG using e.g. imx_usb.

We have a number of platforms that are a combination of a carrier board
and System-on-Module (SoM) that in turn allows for the board to have
different SoCs on it. In some cases, this is handled via board-specific
Kconfig options. In other cases we make use of
CONFIG_SYS_EXTRA_OPTIONS. This latter case however can lead to invalid
configurations as we will not in turn get options that in Kconfig are
selected by or depend on that setting.
To resolve this, make the SoC option a choice in Kconfig and make boards
depend on what they can support. This change opens us up for further
clean-ups in the cases where a single CONFIG_TARGET_xxx can support
different SoCs and today they do not, or do not cleanly do so.

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:
It's a **mistake** to use typedef for structures and pointers.
Besides, using typedef for structures is annoying when you try to make
headers self-contained.
Let's say you have the following function declaration in a header:
void foo(bd_t *bd);
This is not self-contained since bd_t is not defined.
To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
#include <asm/u-boot.h>
void foo(bd_t *bd);
Then, the include direcective pulls in more bloat needlessly.
If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:
struct bd_info;
void foo(struct bd_info *bd);
Right, typedef'ing bd_t is a mistake.
I used coccinelle to generate this commit.
The semantic patch that makes this change is as follows:

The function set_default_env() sets the hashtable flags for import_r().
Formally set_default_env() doesn't accept flags from its callers. In
practice the caller can (un)set the H_INTERACTIVE flag, but it has to be
done using the first character of the function's string argument. Other
flags like H_FORCE can't be set by the caller.
Change the function to accept flags argument. The benefits are:
1. The caller will have to explicitly set the H_INTERACTIVE flag,
instead of un-setting it using a special char in a string.
2. Add the ability to propagate flags from the caller to himport(),
especially the H_FORCE flag from do_env_default() in nvedit.c that
currently gets ignored for "env default -a -f" commands.
3. Flags and messages will not be coupled together. A caller will be
able to set flags without passing a string and vice versa.
Please note:
The propagation of H_FORCE from do_env_default() does not introduce any
functional changes, because currently himport_r() is set to destroy the
old environment regardless if H_FORCE flag is set or not. More changes
are needed to utilize the propagation of H_FORCE.

cpu_cmd() is reading cpu number via simple_strtoul() which is always
unsigned type.
Platform code implementations are not expecting that nr can be negative
and there is not checking in the code for that too.
This patch is using u32 type for cpu number to make sure that platform
code get proper value range.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

When the DDR calibration is enabled, a situation may happen that it
will fail on a few select boards out of a whole production lot. In
particular, after the first write leveling stage, the MPWLDECTRLx
registers will contain a value 0x1nn , for nn usually being 0x7f or
slightly lower.
What this means is that the HW write leveling detected that the DQS
rising edge on one or more bundles arrives slightly _after_ CLK and
therefore when the DDR DRAM samples CLK on the DQS rising edge, the
CLK signal is already high (cfr. AN4467 rev2 Figure 7 on page 18).
The HW write leveling then ends up adding almost an entire cycle (thus
the 0x17f) to the DQS delay, which indeed aligns it, but also triggers
subsequent calibration failure in DQS gating due to this massive offset.
There are two observations here:
- If the MPWLDECTRLx value is corrected from 0x17f to 0x0 , then the
DQS gating passes, the entire calibration passes as well and the
DRAM is perfectly stable even under massive load.
- When using the NXP DRAM calibrator for iMX6/7, the value 0x17f or so
in MPWLDECTRx register is not there, but it is replaced by 0x0 as one
would expect.
Someone from NXP finally explains why, quoting [1]:
"
Having said all that, the DDR Stress Test does something that we
do not advertise to the users. The Stress Test iself looks at the
values of the MPWLDECTRL0/1 fields before reporting results, and
if it sees any filed with a value greater than 200/256 delay
(reported as half-cycle = 0x1 and ABS_OFFSET > 0x48), the DDR
Stress test will reset the Write Leveling delay for this lane
to 0x000 and not report it in the log.
The reason that the DDR Stress test does this is because a delay
of more than 78% a clock cycle means that the DQS edge is arriving
within the JEDEC tolerence of 25% of the clock edge. In most cases,
DQS is arriving < 5% tCK of the SDCLK edge in the early case, and
it does not make sense to delay the DQS strobe almost a full clock
cycle and add extra latency to each Write burst just to make the
two edges align exactly. In this case, we are guilty of making a
decision for the customer without telling them we are doing it so
that we don't have to provide the above explanation to every customer.
They don't need to know it.
"
This patch adds the correction described above, that is if the MPWLDECTRx
value is over 0x148, the value is corrected back to 0x0.

Thomas reported U-Boot failed to build host tools if libfdt-devel
package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.
This commit moves the header code:
include/libfdt.h -> include/linux/libfdt.h
include/libfdt_env.h -> include/linux/libfdt_env.h
and replaces include directives:
#include <libfdt.h> -> #include <linux/libfdt.h>
