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

Instead of loading the zImage kernel and the devicetree separately, switch
to the fitImage format, which is more convenient when working with secure
boot, for example.

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.

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do
not easily transition to Kconfig. In many cases they likely should come
from the device tree instead. Move these out of CONFIG namespace and in
to CFG namespace.

- Make all users of CUSTOM_SYS_INIT_SP_ADDR reference SYS_INIT_SP_ADDR
- Introduce HAS_CUSTOM_SYS_INIT_SP_ADDR to allow for setting the stack
pointer directly, otherwise we use the common calculation.
- On some platforms that were using the standard calculation but did not
set CONFIG_SYS_INIT_RAM_SIZE / CONFIG_SYS_INIT_RAM_ADDR, set them.
- On a small number of platforms that were not subtracting
GENERATED_GBL_DATA_SIZE do so now via the standard calculation.
- CONFIG_SYS_INIT_SP_OFFSET is now widely unused, so remove it from most
board config header files.

This option is used as part of configuring the default environment for a
number of platforms. However, it is always set to 1 and the only time
it is part of Kconfig, it is used in a hard-coded manner. Hard-code the
value in the environment instead.

On the Yocto image there is a single partition and the kernel
and dtb are present in the 'boot' directory.
Change it accordingly so that the board can boot the Yocto
image by default.
Use the generic 'load' command instead, which is able to
read from an ext4 partition.
