The U_BOOT_DRIVER macro creates a list of drivers used at link time, and
all entries here must be unique. This in turn means that all entries in
the code should also be unique in order to not lead to build failures
later with unexpected build combinations. Typically, the problem we have
here is when a driver is obviously based on another driver and didn't
update this particular field and so while the name field reflects
something unique the linker entry itself is not. In a few places this
provides a more suitable string name as well, however.

The maximum length of the board name is not 11 characters
but 14: 11 bytes for the prefix + 3 bytes for the u8 + 1 NULL byte.
Hence, this commit increases the size of the name buffer variable
to 15. Also, this commit fixes the format specifier for the rev_id
variable.

This board is very tight on space in SPL; in fact with my compiler it
ends up just exactly on the wrong side:
spl/u-boot-spl.bin exceeds file size limit:
limit: 0xa000 bytes
actual: 0xa014 bytes
excess: 0x14 bytes
The repeated "lookup and request" pattern in spl_board_init() suggests
a low-hanging fruit for reducing the code size. This reduces the
object size of spl/board/liebherr/btt/btt.o by 300 bytes.
I've left the lack of error handling as-is; there isn't really
anything to do if it fails, so I suppose the printfs are the best that
can be done.

The include file <command.h> does not need anything from <env.h>.
Furthermore, include/env.h itself includes other headers which can lead

The XEA board now has several HW revisions for SoM boards.
This patch provides support for reading this revision ID values in early
u-boot proper as production devices boot via falcon boot with correct DTB
flashed at production (so there is no need to alter SPL).
Additionally, the maximal SPL size (~55KiB) constraint is not allowing
having even simplified FIT support in it.
As a result it was necessary to handle reading GPIOs values solely in
u-boot proper as one configuration (i.e. 'single binary' -
imx28_xea_sb_defconfig) is not using SPL framework.
Moreover, the 'board_som_rev' environment variable will be used to point
correct configuration from the Linux FIT file.
Additionally, as now XEA has its second HW revision - this information is
printed when u-boot proper starts.

The imx287 based XEA board's revision 2 uses GPIO_3_21 for PHY reset
It is safe to keep the GPIO_2_13 as well, as in the SPL SPI1 is not
used for transmission. This simplifies the code, as the proper
configuration is performed either in falcon boot's read DTB or in
u-boot proper (with correct FIT configuration chosen).

1. Convert all linker symbols to char[] type so that we can get the
corresponding address by calling array name 'var' or its address
'&var'. In this way, we can avoid some potential issues[1].
2. Remove unused symbol '_TEXT_BASE'. It has been abandoned and has
not been referenced by any source code.
3. Move '__data_end' to the arch x86's own sections header as it's
only used by x86 arch.
4. Remove some duplicate declared linker symbols. Now we use the
standard header file to declare them.

This change provides the possibility to build XEA (imx287 based) board
U-Boot as a single binary (without support for CONFIG_SPL_FRAMEWORK).
The generated u-boot.sb can be used in the factory environment to for
example perform initial setup or HW testing.
It can be used with 'uuu' utility
(SDPS: boot -f /srv/tftp/xea/u-boot.sb)
In the configs/imx28_xea_defconfig one needs to disable following configs:
# CONFIG_SPL_BLK is not set
# CONFIG_SPL_FRAMEWORK is not set
The board_init_ll() is used in arch/arm/cpu/arm926ejs/mxs/start.S, which
is utilized when CONFIG_SPL_FRAMEWORK is disabled.
However, when it is enabled - the arch/arm/cpu/arm926ejs/start.S is used,
which requires the lowlevel_init() function.

Because of how these symbols work, and the remaining board config.h file
uses, we need to do these at the same time. In some cases we just get
to move rather directly to the defconfigs. A few cases require manual
intervention.
For the case of the eb_cpu5282 we need to select HW_WATCHDOG for the
target, given how it's implemented.
For the cases of m53menlo, dh_imx6, display5, and display5_factory we
disable SPL watchdog support as the particular combination of options
they want would require either more symbols or enabling SPL_DM.

Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to. This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value. Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.
Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g. COLD vs WARM resets). As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).
To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely. Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.
This transformation was done with the following coccinelle patch:

expression argvalue;
@@
- reset_cpu(argvalue)
+ reset_cpu()

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

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:
<smpl>
@@
typedef bd_t;
@@
-bd_t
+struct bd_info

This commit enables imx28 based XEA board's u-boot.sb (SPL) to download
u-boot proper (u-boot.img) via Ymodem protocol.
This is extremely useful in the recovery scenario where u-boot.sb is
downloaded via uuu utility to SDRAM [*], and then one can upload u-boot
proper via serial console to fully debrick the device.
Note - debricking procedure of imx28 devices:
- NXP's original USB based tools (like mxsldr or uuu) expect single
u-boot.sb which is a relic of the old U-Boot (~2013) without SPL and
U-Boot proper distinction.
