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.

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.

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.

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).

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

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

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

lack enough information to apply such a patch in reverse, even

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.

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.

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.
