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.

e307fa9d89 tools: moveconfig: make Slot.poll() more readable with helper methods
The Slot.poll() method is already complicated and a new feature
we are going to add will make it more difficult to understand
the execution flow.

Refactor it with helper methods, .handle_error(), .do_defconfig(),
.do_autoconf(), .do_savedefconfig, and .update_defconfig().

6a9f79f712 tools: moveconfig: allow to run without any CONFIG specified
I found "tools/moveconfig -s" might be useful for defconfig re-sync.

Now, this tools invokes "make savedefconfig" only when it needs to

c8e1b10d07 tools: moveconfig: report when defconfig is updated
There are various factors that determine if the given defconfig is
updated, and it is probably what users are more interested in.

Show the log when the defconfig is updated.  Also, copy the file
only when the file content was really updated to avoid changing
the time stamp needlessly.

5da4f857be tools: moveconfig: report when CONFIGs are removed by savedefconfig
This is a rare case, but there is still possibility that some CONFIG
is moved to the .config, but it is removed by "make savedefconfig".
(For example, it happens when the specified CONFIG has no prompt in
the Kconfig entry, i.e. it is not user-configurable.)

It might be an unexpected case.  So, display the log in this case
(in yellow color to gain user's attention if --color option is given).

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>

b6ef393ad7 tools: moveconfig: allow to give CONFIG names as argument directly
We still pass the input file with CONFIG name, type, default value
in each line, but the last two fields are just ignored by the tool.
So, let's deprecate the input file and allow users to give CONFIG
names directly from the command line.  The types and default values
are automatically detected and handled nicely by the tool.

Going forward, we can use this tool more easily like:

  tools/moveconfig.py CONFIG_FOO CONFIG_BAR

Update the documentation and fix some typos I noticed while I was
working on.

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.

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.".

adb3928f15 ARM: uniphier: support eMMC boot for PH1-LD11 and PH1-LD20
The Boot ROM on PH1-LD11/LD20 exports built-in APIs to load images

of SPL, rather than compiling the whole MMC framework.
