When compiling the current code on GCC 4.8.3, the following warnings
appear:

warning: format '%zu' expects argument of type 'size_t', but argument
2 has type 'long unsigned int' [-Wformat=]

There were many mails about such warnings on different architectures.
This patch limits itself to the nios2 architecture.

The problem is that for the size_t (%zu, %zd, ...) arguments of
printf GCC does not verify the type match to size_t type. It verifies
the type match to the compiler-defined __SIZE_TYPE__ type. Thus, if
size_t is defined different from __SIZE_TYPE__ - warnings inevitably
appear.

There is a comment by Thomas Chou to the (rejected) patch:
http://patchwork.ozlabs.org/patch/272102/
which explains that the older GCC toolchains (gcc-3.4.6 and gcc-4.1.2)
expect size_t to be "unsigned long" and the newer expect it to be
"unsigned int". Thus, no matter how we define size_t - either way
warnings appear when using some GCC version.

By rejecting that patch, a choice was made to prefer older GCC versions
and leave the warnings when building with the newer toolchains.
Personally, I disagree with this choice...

In any case, this patch proposes a way to fix the warnings for any GCC
version. Just define size_t using the __SIZE_TYPE__ compiler-defined
type and the type verification will pass.

I tested that this fixes the warning on GCC 4.8.3. I don't have an
older toolchain to test with, but __SIZE_TYPE__ was definitely defined
in GCC 3.4.6, so it should work there too.

Commit 51148790 added scripts/multiconfig.py written in Python 2
to adjust Kconfig for U-Boot.

It has been hard for Python 3 users because Python 2 and Python 3
are not compatible with each other.

We are not happy about adding a new host tool dependency
(in this case, Python version dependency) for the core build process.
After some discussion, we decided to use only basic tools.

The script may get a bit more unreadable by shell scripting,
but we believe it is worthwhile.

In addition, this commit revives "<board>_config" target that is
equivalent to "<board>_defconfig" for backwards compatibility.
It is annoying to adjust various projects which use U-Boot.

It's not unusual for DHCP servers to take a couple hundred milliseconds
to respond to DHCP discover messages. One possible reason for the delay
can be that the server checks (typically using an ARP request) that the
IP it's about to hand out isn't in use yet. To make matters worse, some
servers may also queue up requests and process them sequentially, which
can cause excessively long delays if clients retry too fast.

Commit f59be6e8 ("net: BOOTP retry timeout improvements") shortened
the retry timeouts significantly, but the BOOTP/DHCP implementation in
U-Boot doesn't handle that well because it will ignore incoming replies
to earlier requests. In one particular setup this increases the time it
takes to obtain a DHCP lease from 630 ms to 8313 ms.

This commit attempts to fix this in two ways. First it increases the
initial retry timeout from 10 ms to 250 ms to give DHCP servers some
more time to respond. At the same time a cache of outstanding DHCP
request IDs is kept so that the implementation will know to continue
transactions even after a retransmission of the DISCOVER message. The
maximum retry timeout is also increased from 1 second to 2 seconds. An
ID cache of size 4 will keep DHCP requests around for 8 seconds (once
the maximum retry timeout has been reached) before dropping them. This
should give servers plenty of time to respond. If it ever turns out
that this isn't enough, the size of the cache can easily be increased.

With this commit the DHCP lease on the above-mentioned setup still takes
longer (1230 ms) than originally, but that's an acceptable compromise to
improve DHCP lease acquisition time for a broader range of setups.

To make it easier to benchmark DHCP in the future, this commit also adds
the time it took to obtain a lease to the final "DHCP client bound to
address x.x.x.x" message.

CONFIG_DEFCONFIG_LIST specifies the default defconfig.
It is used by "make savedefconfig" when .config is missing.
But that's it.  I could not find other useful cases.

As a side effect, CONFIG_DEFCONFIG_LIST="configs/sandbox_defconfig"
is contained in .config of every target board, which some people
think is odd.  So, let's remove it.

Prior to Kconfig, the CPU field of boards.cfg could optionally have
":SPLCPU", like "armv7:arm720t".
(Actually this syntax was only used for Tegra platform.)

Now it is not necessary at all because CPU is defined by
CONFIG_SYS_CPU in Kconfig.

For Tegra platform, the Kconfig option is described as follows:

  config SYS_CPU
          string
          default "arm720t" if SPL_BUILD
          default "armv7" if !SPL_BUILD

"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.

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.
