When using a list of writeable variables, the initial values come
from the built-in default environment since commit 5ab81058364b ("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 b16fd7f75f6d ("imx6q: acc: Remove misuse
of env is nowhere driver").

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.

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.

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.

Two conflicting bootcmds were included in the environment.
Streamline to defining the bootcmd only in the env file.

Currently, it is recommended to move from CFG_EXTRA_ENV_SETTINGS to
an env file, so do the conversion.

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.

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.

This is supposed to be a build-system flag. Move it there so we can
define it before linux/kconfig.h is included.

uses version 1.2 of NXP's i.MX7D DRAM Register Programming Aid
spreadsheet.
This updated DDR initialization fixes occasional system freeze.

- 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.
