f626382d08 smegw01: Remove misuse of CONFIG_ENV_IS_NOWHERE
When using a list of writeable variables, the initial values come
from the built-in default environment since commit 5ab8105836 ("env:
Complete generic support for writable list").

Remove unnecessary misuse of CONFIG_ENV_IS_NOWHERE as default environment.

Based on the fix done by commit b16fd7f75f ("imx6q: acc: Remove misuse
of env is nowhere driver").

fa5bde3760 smegw01: Fix inverted CONFIG_SYS_BOOT_LOCKED logic
CONFIG_SYS_BOOT_LOCKED means that a restricted boot environment will
be used. In this case, hab_auth_img_or_fail should be called to prevent
U-Boot to continue running when the fitImage authentication fails.

Fix the logic accordingly.

Additionally, select CONFIG_SYS_BOOT_LOCKED by default.

62a3c66a7c smegw01: Use CONFIG_SYS_LOAD_ADDR for loading fitImage
Set CONFIG_SYS_LOAD_ADDR=0x88000000 and use this address for
loading fitImage.

Also pass the standard CONFIG_BOOTFILE option to indicate
the fitImage file.

5fa30f2351 smegw01: Fix wrong symbol override
board_mmc_get_env_part() is not called as the default implementation
of mmc_get_env_part() is used.

Fix this problem by directly calling mmc_get_env_part() instead.

ea99d227f9 smegw01: Read the second MAC address
Currently, only the first MAC address is read from the fuses.

The second MAC address is not read and Linux assigns a random one.

To prevent this behavior, read the second MAC address from the fuses
and store it into the eth1addr environment variable so that it
can be passed to Linux.

31c6c79a01 smegw01: Enable EMMC boot from multiple partitions
GPT Partition labels are used for determining the right
root filesystem to boot from.

The U-Boot environment is configured to reside in the eMMC hardware
boot partition we are currently booted from.

This should enable a dual copy approach for upgrading the bootloader.
One can overwrite the inactive hardware partition with new bootloader
and environment and afterwards switch the eMMC boot partition for an
atomic bootloader switch.

148b8bb4b6 imx: Finish migration of IMX_CONFIG to Kconfig
- Provide a default Kconfig value of the default script
- Largely continue to define this via the board Kconfig file
- For the boards that select a script based on defconfig rather than
  TARGET, keep this within the defconfig.
