Currently the LVDS backlight does not work in U-Boot after a “reboot” comand
in the kernel.
This problem occurs because the kernel uses this pin in PWM mode and U-Boot
does not configure the backlight pin as GPIO functionality.
So fix the problem by explicitly configuring the backlight pin as GPIO in
U-Boot.

Memory barriers are proven to be a requirement for both compiler and
real hardware to properly serialize access to critical data.
For example if CPU or data bus it uses may do reordering of data
accesses absence of memory barriers might easily lead to very subtle and
hard to debug data corruptions.
This implementation was heavily borrowed from up to date Linux kernel.

Now when we have support of IOC (IO-Coherency block) cahce operations
on regions are tuned to not be dummy stubs if IOC was found and enabled
in the core. That makes flush_dcache_range() useless for our purposes
here. And since we do need to flush modified reset vector to at least L2
cache (AKA SLC) so other cores will see it via its L1 instruction cache
we're using always functional flush_dcache_all() here.

According to ARC HS databook it is required to flush and disable
caches prior programming IOC registers. Otherwise ongoing coherent
memory operations may not observe the coherency protocols as
expected.
But since in ARC HS v2.1 there's no way to disable SLC (AKA L2 cache)
we're doing our best flushing and invalidating it.

invalidate_dcache_all() could be used in different use-cases
and what is especially important most of those cases won't be
related to DMAed data to or from peripherals, i.e. we'll be doing
invalidation of data used purely by CPU cores.
Given that IOC engine only snoops data that goes through DMA
we need to care ourselves about data used only by CPU cores
and so remove dependency on IOC from invalidate_dcache_all()
and always do real invalidation.

In case we have restarted u-boot there is a chance that environment
buffer contains old environment (from the previous boot). If UBI volume
is zero size, ubi_volume_read() doesn't modify the buffer and exits
successfully.
We need to clear buffer manually before reading it from UBI, so the
invalid CRC will cause setting default environment in case that the UBI
volume is zero size.

The sed script, tools/scripts/define2mk.sed, converts config defines
from C headers into include/autoconf.mk for the use in Makefiles.
I found the tool adds quotes around negative integer values.
For example, at the point of the v2016.07-rc1 tag,
include/configs/microblaze-generic.h defines
#define CONFIG_BOOTDELAY -1 /* -1 disables auto-boot */
Because it is an integer option, it should be converted to:
CONFIG_BOOTDELAY=-1
But, the script actually converts it to:
CONFIG_BOOTDELAY="-1"
This is a fatal problem for the tools/moveconfig.py because it parses
include/autoconf.mk for the config defines from the board headers.
CONFIG_BOOTDELAY="-1" is considered as a string type option and it
is dropped due to the type mismatch from the entry in Kconfig.
This commit fixes the script so that the tools/moveconfig.py can
correctly convert integer options with a negative value.

This option allows the 'make autoconf.mk' step to run against a former
repo state, while the savedefconfig step runs against the current repo
state. This is convenient for the case where something in the Kconfig
has changed such that the defconfig is no longer complete with the new
Kconfigs. This feature allows the .config to be built assuming those old
Kconfigs, but then savedefconfig based on the new state of the Kconfigs.
If in doubt, always specify this switch. It will always do the right
thing even if not required, but if it was required and you don't use it,
the moved configs will be incorrect. When not using this switch, you
must very carefully evaluate that all moved configs are correct.
