310ae37edb Fix bad return value checks (detected with Coccinelle)
In the "Getting Started with Coccinelle - KVM edition" presentation that
has been held by Julia Lawall at the KVM forum 2015 (see the slides at
http://events.linuxfoundation.org/sites/events/files/slides/tutorial_kvm_0.pdf),
she pointed out some bad return value checks in U-Boot that can be
detected with Coccinelle by using the following config file:

@@
identifier x,y;
identifier f;
statement S;
@@
x = f(...);
(
 if (x < 0) S
|
 if (
-     y
+     x
 < 0) S
)

This patch now fixes these issues.

0219e4bfb4 Fix variation in timestamps caused by timezone differences.
When building with SOURCE_DATE_EPOCH set, avoid use of mktime in
default_image.c, which converts the timestamp into localtime. This
causes variation based on timezone when building u-boot.img and
u-boot-sunxi-with-spl.bin targets.

e29f1db3dd tools: kwboot: Add support for UART boot mode patching for Armada XP/38x
Currently, kwboot only allows dynamic UART boot mode patching for SoCs
with header version 0 (Orion, Kirkwood). This patch now enables this "-p"
feature also for SoCs with header version 1 (Armada XP / 38x etc). With
this its possible now to use the UART boot mode without on images that
are generated for other boot devices, like SPI. So no need to change
BOOT_FROM to "uart" for UART xmodem booting any more.

a188438175 sunxi: (mksunxiboot) signature to indicate "sunxi" SPL variant
This patch follows up on a discussion of ways to improve support
for the sunxi FEL ("USB boot") mechanism, especially with regard
to boot scripts, see:
https://groups.google.com/d/msg/linux-sunxi/wBEGUoLNRro/rHGq6nSYCQAJ

The idea is to convert the (currently unused) "pad" bytes in the
SPL header into an area where data can be passed to U-Boot. To
do this safely, we have to make sure that we're actually using
our "sunxi" flavor of the SPL, and not the Allwinner boot0.

The modified mksunxiboot introduces a special signature to the
SPL header in place of the "pub_head_size" field. This can be
used to reliably distinguish between compatible versions of sunxi
SPL and anything else (older variants or Allwinner's boot0).

3e4dad5032 tools: gen_eth_addr: add getpid() to time(0) to avoid duplicated seed
As 'time(0) | getpid()' will have a lot of duplicated value. It is not a
expected behavior. We expect different value for the seed when when run

So this patch will left shift the getpid() and add to time(0). That
avoid duplicated value.

8270e3c12e buildman: Improve the config comparison feature

feature is less useful than it could be. There is no summary by architecture

Correct these deficiencies so that it is possible to see exactly what is

Note that 'buildman -b <branch> -C' is recommended for any build where you
will be comparing configuration. Without -C the correct configuration will
not be reported since changes will often not be picked up.

8d3595a42b Revert "patman: use -D option for git format-patch"
This reverts commit 19b4a33698.

Since that commit, patman generates useless patches for file removal;
"git format -D" prints only the header but not the diff when deleting
files, and "git am" always refuses such patches.

The following is the quotation from "man git-format-patch":

  -D, --irreversible-delete
    Omit the preimage for deletes, i.e. print only the header but
    not the diff between the preimage and /dev/null. The resulting
    patch is not meant to be applied with patch nor git apply; this
    is solely for people who want to just concentrate on reviewing
    the text after the change. In addition, the output obviously
    lack enough information to apply such a patch in reverse, even
    manually, hence the name of the option.

f86f0c1897 x86: ifdtool: Drop microcode from the device tree when collating
When ifdtool collates the microcode into one place it effectively creates
a copy of the 'data' properties in the device tree microcode nodes. This
is wasteful since we now have two copies of the microcode in the ROM.

To avoid this, remove the microcode data from the device tree and shrink it
down. This means that there is only one copy and the overall ROM space used
by the microcode does not increase.

b098032387 x86: ifdtool: Support collating microcode into one place
The Intel Firmware Support Package (FSP) requires that microcode be provided
very early before the device tree can be scanned. We already support adding
a pointer to the microcode data in a place where early init code can access.

However this just points into the device tree and can only point to a single
lot of microcode. For boards which may have different CPU types we must
support multiple microcodes and pass all of them to the FSP in one place.

Enhance ifdtool to scan all the microcode, place it together in the ROM and
update the microcode pointer to point there. This allows us to pass multiple
microcode blocks to the FSP using its existing API.

Enable the flag in the Makefile so that this feature is used by default for
all boards.

f3f431a712 Reproducible U-Boot build support, using SOURCE_DATE_EPOCH
In order to achieve reproducible builds in U-Boot, timestamps that are defined
at build-time have to be somewhat eliminated. The SOURCE_DATE_EPOCH environment
variable allows setting a fixed value for those timestamps.

Simply by setting SOURCE_DATE_EPOCH to a fixed value, a number of targets can be
built reproducibly. This is the case for e.g. sunxi devices.

However, some other devices might need some more tweaks, especially regarding
the image generation tools.

92a655c326 mkimage: Set up a file size parameter and keep it updated
Some functions called by mkimage would like to know the output file size.
Initially this is the same as the input file size, but it may be affected by
adding headers, etc.

Add this information to the image parameters.

1043d0a029 fdt: Add fdtgrep tool
This tool allows us to extract subsets of a device tree file. It is used by
the SPL vuild, which needs to cut down the device tree size for use in
limited memory.

This tool was originally written for libfdt but it has not been accepted
upstream, so for now, include it in U-Boot. Several utilfdt library
functions been included inline here.

If fdtgrep is eventually accepted in libfdt then we can bring that version
of libfdt in here, and drop fdtgrep (requiring that fdtgrep is provided by
the user).

If it is not accepted then another approach would be to write a special
tool for chopping down device tree files for SPL. While it would use the
same libfdt support, it would be less code than fdtgrep.c because it would
not have general-purpose functions.

Another approach (which was used with v1 of this series) is to sprinkler all
the device tree files with #ifdef. I don't like that idea.

5b9d44df23 mkimage: Display a better list of available image types
Offer to display the available image types in help. Also, rather than
hacking the genimg_get_type_id() function to display a list of types,
do this in the tool. Also, sort the list.

The list of image types is quite long, and hard to discover. Print it out
when we show help information.
