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.

5c86a8f7a1 imx: Don't define __ASSEMBLY__ in source files
This is supposed to be a build-system flag. Move it there so we can
define it before linux/kconfig.h is included.

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.
