c7d8db66ff board: axs10x: Flush entire cache after programming reset vector
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.

a4a43fcf9c arc/cache: Flush & invalidate all caches right before enabling IOC
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.

bd91508b50 arc/cache: really do invalidate_dcache_all() even if IOC exists
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.

c1f51e0f3e common: env_ubi: Clear environment buffer before reading
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.

cd51878e34 tools: fix define2mk.sed to not add quotes around negative integers
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.

6b96c1a1ca tools: moveconfig: Add a new --git-ref option
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.

1d085568b3 tools: moveconfig: display log atomically in more readable format
Before this commit, the log was displayed in the format:

<defconfig_name>   : <action1>
<defconfig_name>   : <action2>
<defconfig_name>   : <action3>

When we move multiple CONFIGs at the same time, we see as many
<defconfig_name> strings as actions for every defconfig, which is
redundant information.

Moreover, since normal log and error log are displayed separately,
Messages from different threads could be mixed, like this:

<foo>              : <action1>
<foo>              : <action2>
<bar>              : <action1>
<bar>              : <action2>
<foo>              : <error_log>

This commit makes sure to call "print" once a defconfig, which
enables atomic logging for each defconfig.  It also makes it
possible to refactor the log format as follows:

<foo_defconfig>
    <action1>
    <action2>
    <error_log>

<bar_defconfig>
    <action1>
    <action2>

cc008299f8 tools: moveconfig: do not rely on type and default value given by users
Commit 96464badc7 ("moveconfig: Always run savedefconfig on the
moved config") changed the work flow of this tool a lot from the
original intention when this tool was designed first.

Since then, before running this tool, users must edit the Kconfig to
add the menu entries for the configs they are moving.  It means users
had already specified the type and the default value for each CONFIG
via its Kconfig entry.  Nevertheless, users are still required to
dictate the same type and the default value in the input file.  This
is tedious to use.  So, my idea here is to deprecate the latter.

Before moving forward with it, there is one issue worth mentioning;
since the savedefconfig re-sync was introduced, this tool has not
been able to move bool options with "default y".  Joe sent a patch
to solve this problem about a year ago, but it was not applied for
some reasons.  Now, he came back with an updated patch, so this
problem will be fixed soon.

For other use cases, I see no reason to require redundant dictation
in the input file.  Instead, the tool can know the types and default
values by parsing the .config file.

This commit changes the tool to use the CONFIG names, but ignore the
types and default values given by the input file.

This commit also fixes one bug.  Prior to this commit, it could not
move an integer-typed CONFIG with value 1.

For example, assume we are moving CONFIG_CONS_INDEX.  Please note
this is an integer type option.

Many board headers define this CONFIG as 1.

  #define CONFIG_CONS_INDEX    1

It will be converted to

  CONFIG_CONS_INDEX=y

and moved to include/autoconf.mk, by the tools/scripts/define2mk.sed.
It will cause "make savedefconfig" to fail due to the type conflict.

This commit takes care of it by detecting the type and converting the
CONFIG value correctly.

This does not explain what is wrong.  Show an appropriate error
message "source tree is not clean, please run 'make mrproper'"
in such a situation.

90ed6cba51 tools: moveconfig: check compilers before starting defconfig walk
Since commit 25400090b1 ("moveconfig: Print a message for
missing compiler"), this tool parses an error message every time an
error occurs during the process in order to detect missing compiler.

Instead of that, we can look for compilers in the PATH environment
only once before starting the defconfig walk.  If a desired compiler
is missing, "make include/config/auto.conf" will apparently fail for
that architecture.  So, the tool can just skip those board, showing
"Compiler is missing.  Do nothing.".
