506df9dc58 treewide: rework linker symbol declarations in sections header
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.

[1] This patch fixes the boot failure on MIPS target. Error log:
SPL: Image overlaps SPL

e4c3ce7e28 CONFIG_SYS_CLK_FREQ: Consistently be static or get_board_sys_clk()
This CONFIG option is used in one of two ways.  The first way is that it
is defined to a static value, of an unsigned long size.  The second way
is that it is defined to something, typically a function, to determine
this value at run time.

However, in a few cases that function returns a static value.  Change
that to using the static value directly.

In the case of using something at run time, convert everything to using
a function of the same name and prototype.  This will allow for further
cleanups.

Finally, we have a few cases where the function is just not used, so
drop it.

efb5dab7ba nxp: Migrate CONFIG_DDR_CLK_FREQ to Kconfig
As this symbol can either be a fixed value or the function
get_board_ddr_clk, migration is tricky.  Introduce a choice of DYNAMIC
or STATIC_DDR_CLK_FREQ.  If DYNAMIC, we continue to use the board
defined get_board_ddr_clk function.  If STATIC, set CONFIG_DDR_CLK_FREQ
to that value and now include/clock_legacy.h contains the function
prototype or defines get_board_ddr_clk() to that static value.  Update
callers to test for DYNAMIC or STATIC.

2147a16983 dm: i2c: use CONFIG_IS_ENABLED macro for DM_I2C/DM_I2C_GPIO
Use CONFIG_IS_ENABLED() macro, which provides more convenient
way to check $(SPL)DM_I2C/$(SPL)DM_I2C_GPIO configs

- 1 if CONFIG_SPL_BUILD is defined and CONFIG_SPL_DM_I2C is set to 'y',
- 0 otherwise.

b75d8dc564 treewide: convert bd_t to struct bd_info by coccinelle
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
  </smpl>

f668c52033 arm: ls1021a: Add timer_init() in board_init_f for SPL
I2C is used to access DDR SPD in the DDR initialization for SPL. In
i2c_write process, get_timer() will be called. In board_init_f for SPL,
timer_init() is not called before. The system counter is not enabled and
the counter frequency is not set to 12.5MHz in SPL. The parameters for
do_div() are zero too.

It could not be found until CONFIG_USE_PRIVATE_LIBGCC is enabled in
default. When CONFIG_USE_PRIVATE_LIBGCC is enabled, U-Boot will use its
own set of libgcc functions. As the parameters for do_div() are zero,
__div0 will be called. Then the processor will stay in an endless loop
after calling hang().

This patch will add timer_init() in board_init_f for SPL and fix a
series of issues it caused.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

This patch reverts to use ge0_clk125 for eTSEC clock muxing. For SAI and
CAN which are pin multiplexed with RGMII1 in EC1 of RCW, ge2_clk125 will
be used via hwconfig.

22d69fd7a8 imx: ls102xa: Remove reference to gdata
The global_data pointer (gd) has already been set before board_init_f()
is called. We should not assign it again. We should also not use gdata since
it is going away.

660673af4f ARM: ls102xa: Setting device's stream id for SMMUs.
LS1 has 4 SMMUs for address translation of the masters. All the
SMMUs' stream IDs are 8-bit. The address translation depends on the
stream ID of the incoming transaction.
Each master has unique stream ID assigned to it and is configurable
through SCFG registers. The stream ID for the masters is identical
and share the same register field of STREAM ID registers.

e87f3b308c ARM: ls102xa: allow all the peripheral access permission as R/W.
The Central Security Unit (CSU) allows secure world software to
change the default access control policies of peripherals/bus
slaves, determining which bus masters may access them. This
allows peripherals to be separated into distinct security domains.
Combined with SMMU configuration of the system masters privileges,
these features provide protection against indirect unauthorized
access to data.

For now we configure all the peripheral access permissions as R/W.
