.gitignore: clean-up unnecessary entries

There have been /errlog and /reloc_off in the top level .gitignore
since commit 1b4aaffe added it about 7 years ago.

But they are no longer generated.

sh: unify sh2/sh3/sh4 linker scripts

The linker scripts of sh2/sh3/sh4 are almost the same.
The difference among them is essentially only one line.

They can be consolidated into a single file, arch/sh/cpu/u-boot.lds
by re-writing the diffrent line as follows:

	KEEP(*/start.o	(.text))

spl: nand: read only in the size of image_header on the first access

with sizeof(*header).

serial: ns16550: drop CONFIG_OMAP1610 from the special case

If CONFIG_OMAP1610 is defined, the code returning the fixed value (26)
is enabled. But this case is covered by the following code.

(CONFIG_SYS_NS16550_CLK + (gd->baudrate * (MODE_X_DIV / 2))) /
    (MODE_X_DIV * gd->baudrate)
= (48000000 + (115200 * (16 / 2))) / (16 * 115200)
= 48921600 / 1843200
= 26

The "#ifdef CONFIG_OMAP1610" was added by commit 6f21347d more than
ten years ago. In those days, the divide-and-round was not used.
I guess that is why this weird code was added here.

add .mailmap for proper git-shortlog output

This is the first version of .mailmap created by hand.
Please see "man git-shortlog" for what this commit is trying to do.

Without this file, for example, "git shortlog -n -s" shows as follows:

  2693  Wolfgang Denk     <------
  1002  Stefan Roese      <------
   811  wdenk             <------

     [snip]
   177  Matthias Fuchs
   154  stroese           <------
   153  Timur Tabi

And then, with this file, it shows as follows:

Add .mailmap file and a tool to maintain it

scripts: add mailmapper, a tool to create/update mailmap file

This tool helps to create/update the mailmap file.

It runs 'git shortlog' internally and searches differently spelled author
names which share the same email address. The author name with the most
commits is asuumed to be a canonical real name. If the number of commits
from the cananonical name is equal to or greater than 'MIN_COMMITS' (=50),
the entry for the cananical name will be output. ('MIN_COMMITS' is used
here because we do not want to create a fat mailmap by adding every author
with only a few commits.)

If there exists a mailmap file specified by the mailmap.file configuration
options or '.mailmap' at the toplevel of the repository, it is used as
a base file.

The base file and the newly added entries are merged together and sorted
alphabetically (but the comment block is kept untouched), and then printed
to standard output.

 Usage
 -----

  scripts/mailmapper

prints the mailmapping to standard output.

  scripts/mailmapper > tmp; mv tmp .mailmap

will be useful for updating '.mailmap' file.

kbuild: move extra gcc checks to scripts/Makefile.extrawarn

This commit was imported from Linux Kernel:
commit a86fe353 written by me.

W=... provides extra gcc checks.

Having such code in scripts/Makefile.build results in the same flags
being added to KBUILD_CFLAGS multiple times becuase
scripts/Makefile.build is invoked every time Kbuild descends into
the subdirectories.

Since the top Makefile is already too cluttered, this commit moves
all of extra gcc check stuff to a new file scripts/Makefile.extrawarn,
which is included from the top Makefile.

Kbuild: sync with Linux 3.16-rc1

The merge window for Linux 3.16 is closed and Linux 3.16-rc1 is out now.

During the merge window, various Kbuild-related updates were merged into
the upstream.

This series imports them to U-Boot.

kbuild: sync mixed targets handling with Linux 3.16-rc1

"make %_config all" was supported for the first time in U-Boot:
  commit 53bca5ab
  kbuild: support simultaneous board configuration and "make all"

Surprisingly it had not been working in Linux Kernel for a long time.

So I sent back the patch to the Linux Kbuild community and it was
accepted with a little code improvement, at commit 9319f453.

Now, you can do "make defconfig all" or "make %_defconfig all"
in Linux too.

This commit updates some scripts to fill the code-diff
between Linux and U-Boot.
