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

9395eb05ee imx: bootaux: change names of MACROs used to boot MCU on iMX devices
The current bootaux supports i.MX8M and i.MX93, but the name "_M4_"
implies that the SoCs have Cortex-M4. Actually i.MX8MM/Q use Cortex-M4,
i.MX8MN/P use Cortex-M7, i.MX93 use Cortex-M33, so use "_MCU_" in place
of "_M4_" to simplify the naming.

9d8665b709 i2c: Convert CONFIG_POWER_I2C et al to Kconfig
This converts the following to Kconfig:
   CONFIG_POWER_I2C
   CONFIG_POWER_LEGACY

They are handled at the same time due to a dependency between them.
Update the Makefile rule to use legacy power only in U-Boot proper.
Unfortunately a separate rule is needed in SPL to be able to build
legacy power.  Add SPL related symbols for both, to allow for SPL-only
usage.

29d7153ec3 power: Rename CONFIG_POWER to CONFIG_POWER_LEGACY

been converted to driver model.

We want to add a new option to enable power support, so we can use a

a particular implementation of power.

Also update the pmic.h header file so it either includes the legacy
API or the driver model one.

35b65dd8ef reset: Remove addr parameter from reset_cpu()
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()

    @@
    identifier argname;
    type argtype;

    - reset_cpu(argtype argname)
    + reset_cpu(void)

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>

Adjust the process to allow OPTEE in the middle of first bank.

When OPTEE memory is removed from first bank, it may split the first bank

Since the default CONFIG_NR_DRAM_BANKS is 4, it is enough, just enlarge
i.MX8MP evk to default to avoid issue.
