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

Fixes: 1b8a1be1a1 ("spl: spl_legacy: Fix spl_end address")

1b4c3e6125 imx8mn-var-som: adjust PHY reset gpios according to hardware configuration
For SOM with the EC configuration, the ethernet PHY is located on the
SOM itself, and connected to the CPU ethernet controller. It has a
reset line controlled via GPIO1_IO9. In this configuration, the PHY
located on the carrier board is not connected to anything and is
therefore not used.

For SOM without EC configuration, the ethernet PHY on the carrier
board is connected to the CPU ethernet controller. It has a reset line
controlled via the GPIO expander PCA9534_IO5.

The hardware configuration (EC) is determined at runtime by
reading from the SOM EEPROM.

To support both hardware configurations (EC and non-EC), adjust/fix
the PHY reset gpios according to the hardware configuration
read at runtime from the SOM EEPROM. This adjustement is done in
U-Boot (OF_BOARD_FIXUP) and kernel (OF_BOARD_SETUP) device trees.

93145335fb nxp: Make board/freescale/common/Kconfig safe to include once in arch/Kconfig
The way that we use this file currently means that we have to guard it

platforms, including non-reference platforms.  Make all options in it

pinctrl_wdog already marked u-boot,dm-spl, so clean up board code.

The set_wdog_reset() function is not necessary as this is handled by
the imx_watchdog.c driver due to the 'fsl,ext-reset-output' property
being set.

401d1c4f5d common: Drop asm/global_data.h from common header
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.

it returns the right size in _bytes_ and modifies the printf call so the

9452d58e10 arm: dart6ul: enable DM_ETH for the dart6ul
This patch converts the dart6ul ethernet support to DM_ETH and cleans
up the legacy ethernet code. The clean up, more specifically:

* moves the fec2 node and pin definition to the carrier board DTS
  since the phy associated with it is on the carrier board and not on
  the SoM;
* add the reset pin associated to each phy;
* separate the ethernet, mdio and reset pins of each fec so that they
  are easier to reference;
* add clock properties to the phy nodes since they are connected to the
  50Mhz ENET[12]_TX_CLK clock of the SoC;
* remove CONFIG_BOARD_EARLY_INIT_F since the function is now empty.

37648b600c arm: dart6ul: read and print SoM info from eeprom on startup
The dart6ul has an i2c eeprom at 0x50 which contains, among other
things, the manufacturing/revision/options info of the SoM. This patch
replaces the current checkboard() implementation with a more
exhaustive one based on the content of the eeprom.

Since this code uses the new driver model, some changes were also
required in the DTS to make the nodes related to i2c available before
relocation.

This code was inspired from the supported u-boot code from Variscite
which can be found here:

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>

90526e9fba common: Drop net.h from common header
Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.

Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.
