History
Marek Behún b26334824b board: freescale: various boards: Let env subsystem set gd->env_addr 
Various freescale boards set gd->env_addr to default_environment in
board_init(), conditional on CONFIG_ENV_IS_NOWHERE, but this is
redundant, since it is done by env_init() before board_init() is called.

Let the env subsystem handle this.

Overview
--------
QorIQ LS1012A Development System (LS1012AQDS) is a high-performance
development platform, with a complete debugging environment.
The LS1012AQDS board supports the QorIQ LS1012A processor and is
optimized to support the high-bandwidth DDR3L memory and
a full complement of high-speed SerDes ports.

LS1012A SoC Overview
--------------------
Please refer arch/arm/cpu/armv8/fsl-layerscape/doc/README.soc for LS1012A
SoC overview.

LS1012AQDS board Overview
