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.

Select DM_ETH_PHY so that the reset-gpios property of the ethphy node
can be used.
Also select DM_PCA953X, which is needed for resetting the
ethernet PHY on the carrier board via the PCA9534 I/O expander.
Commit 4e5114daf9 ("imx8mn: synchronise device tree with linux") did
synchronise device tree with linux, which in effect removed obsolete
PHY reset properties and replaced them with new mdio DM
properties. But the commit didn't activate DM_ETH_PHY or DM_PCA953X.
Fixes: 4e5114daf9 ("imx8mn: synchronise device tree with linux")

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.

This converts the following to Kconfig:
CONFIG_SYS_MONITOR_LEN
To do this, we set a default of 0 for everyone because there are a
number of cases where we define CONFIG_SYS_MONITOR_LEN but the only
impact is that we set TOTAL_MALLOC_LEN to be CONFIG_SYS_MALLOC_LEN +
CONFIG_ENV_SIZE, so we must continue to allow all boards to set this
value. Update the SPL code to use 200 KB as the default raw U-Boot size
directly, if we don't have a real CONFIG_SYS_MONITOR_LEN value.

The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE
and this makes it imposible to use CONFIG_VAL().
Rename it to resolve this problem.

This converts the following to Kconfig:
CONFIG_SYS_BOOTM_LEN
As part of this, rework error handling in boot/bootm.c so that we pass
the buffer size to handle_decomp_error as CONFIG_SYS_BOOTM_LEN will not
be available to host tools but we do know the size that we passed to
malloc().

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

This converts the following to Kconfig:

CONFIG_SYS_SPL_MALLOC_START
We introduce a default value here as well, and CONFIG_SYS_SPL_MALLOC to
control if we have a malloc pool or not.

This converts the following to Kconfig:

Note that the da850evm platforms were violating the "only use one" rule
here, and so now hard-code their BSS limit.

This converts the following to Kconfig:

Note that we need to make TPL_MAX_SIZE be hex, and so move and convert the
existing places.

As the CI test for stopping platforms from being merged that were
defining symbols that had Kconfig entries, a small number of symbols
needed to be migrated again. Do so, and catch two cases the README
should also have been updated but was not.
