This option delays loading of the environment until later, so that only the
default environment will be available to U-Boot.
This can address the security risk of untrusted data being used during boot.
Any time you load untrusted data you expose yourself to a bug in the
code. The attacker gets to choose the data so can sometimes carefully
craft it to exploit a bug. We try to avoid touching user-controlled
data during a verified boot unless strictly necessary. Since the
default environment is good enough in this case (or you would just
change it), this gets around the problem by just not loading the
environment.
When CONFIG_DELAY_ENVIRONMENT is defined, it is convenient to have a
run-time way of enabling loading of the environment. Add this to the
fdt as /config/delay-environment.

In Cortex-A15 architecture, when we run cache invalidate
the cache clean operation executes automatically.
So if there are any dirty cache lines before disabling the L2 cache
these will be synchronized with the main memory when
invalidate_dcache_all() runs in the last part of U-boot
The two functions after flush_dcache_all is using the stack. So this
data will be on the cache. After disable when invalidate is called the
data will be flushed from cache to memory. This corrupts the stack in
invalida_dcache_all. So this change is required to avoid the u-boot
hang.
So flush has to be done just before clearing CR_C bit

These GPMC_CS defines are a leftover from prior gpmc_init(). Commit 187af954
removed the need for these definitions but missed to remove them.

Conflicts:
drivers/power/power_fsl.c
include/configs/mx35pdk.h
include/configs/mx53loco.h
include/configs/woodburn_common.h
board/woodburn/woodburn.c
These boards still use the old old PMIC framework, so they
do not merge properly after the power framework was merged into
mainline.
Fix all conflicts and update woodburn to use Power Framework.

Use a generic 'dram_vals[]' array that has the full initialization
sequence and rename the initialization method so it doesn't has a
frequency on its name.

The MXS SPL didn't mark local functions "static". Fix it. This also makes the
SPL smaller by roughly 300 bytes.

The memory setup code adjusted the VDDD voltage. Remove this adjustment
and configure the VDDD voltage correctly in the power supply setup code.

Implement common function to setup the VDDIO, VDDD and VDDA voltage.
Right now, there are two almost identical functions to setup VDDIO
and VDDD, which is prone to breakage. Pull out the differences into
constant structure and pass them as an argument to the common function.
Moreover, the function has almost identical loops for setting higher
and lower VDDx voltage. Merge these two loops.
