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.

fc1b8e1e7e imx8mn-var-som: read and print SoM infos from eeprom on startup
Enable support to read and display configuration/manufacturing infos
from 4Kbit EEPROM located on SOM board.

Note: CONFIG_DISPLAY_BOARDINFO is automatically selected for ARM arch.

762592cb5c Correct SPL uses of FEC_MXC
This converts 4 usages of this option to the non-SPL form, since there is
no SPL_FEC_MXC defined in Kconfig

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
in every platform Kconfig.  But it is also required in all NXP
platforms, including non-reference platforms.  Make all options in it
have appropriate dependencies so that we can include it a single time
under arch/Kconfig

ae75489c48 imx: imx8mn_var_som: clean up board watchdog code
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.

bb9e14cfd0 imx: imx8mn_var_som: enable DM_SERIAL
Enable CONFIG_DM_SERIAL. uart and its pinmux was already
marked with u-boot,dm-spl.
Move preloader_console_init after spl_init to make sure driver
model work.
