move fdtdec_get_int() out of lib/fdtdec.c into lib/fdtdec_common.c
as this function is also used, if CONFIG_OF_CONTROL is not
used. Poped up on the ids8313 board using signed FIT images,
and activating CONFIG_SYS_GENERIC_BOARD. Without this patch
it shows on boot:
No valid FDT found - please append one to U-Boot binary, use u-boot-dtb.bin or define CONFIG_OF_EMBED. For sandbox, use -d <file.dtb>
With this patch, it boots again with CONFIG_SYS_GENERIC_BOARD
enabled.

commit 18b06652cd "tools: include u-boot version of sha256.h"
unconditionally forced the sha256.h from u-boot to be used
for tools instead of the host version. This is fragile though
as it will also include the host version. Therefore move it
to include/u-boot to join u-boot/md5.h etc which were renamed
for the same reason.

It has been observed that fit_check_format() will fail when passed a
corrupt FIT image. This was tracked down to _fdt_string_eq():
return (strlen(p) == len) && (memcmp(p, s, len) == 0);
In the case of a corrupt FIT image one can't depend on 'p' being NULL
terminated. I changed it to use strnlen() to fix the issue.

It seems the code tries to trick the compiler the argument
is actually used. However compilers became too smart to
fool them so easily an now warn. Gcc and clang don't seem
to emit a warning when the argument is unused. If so it
should be decorated with unused / (void).

When writing values into an FDT it is possible that there will be

This adds driver support for the TPS65090 PMU. Support includes
hooking into the pmic infrastructure so that the pmic commands
can be used on the console. The TPS65090 supports the following
functionality:
- fet enable/disable/querying
- getting and setting of charge state
Even though it is connected to the pmic infrastructure it does
not hook into the pmic charging charging infrastructure.
The device tree binding is from Linux, but only a small subset of
functionality is supported.

Commit 2842c1c24269a05142802d25520e7cb9035e456c introduced lib/sha256 into
mkimage. Since then it will be compiled with HOSTCC which may produce errors
on some systems. Most BSD systems (like OS X for me) do not ship a
linux/string.h which will lead to take the U-Boot provided
include/linux/string.h in the end. This header howver is completely wrong
here. Just take the string.h if compiling with HOSTCC and linux/string.h when
not.

This patch adds support to generate UUID (Universally Unique Identifier)
in version 4 based on RFC4122, which is randomly.
Source: https://www.ietf.org/rfc/rfc4122.txt
Changes:
- new configs:
- CONFIG_LIB_UUID for compile lib/uuid.c
- CONFIG_RANDOM_UUID for functions gen_rand_uuid() and gen_rand_uuid_str()
- add configs dependency to include/config_fallbacks.h for lib uuid.
lib/uuid.c:
- add gen_rand_uuid() - this function writes 16 bytes len binary representation
of UUID v4 to the memory at given address.
- add gen_rand_uuid_str() - this function writes 37 bytes len hexadecimal
ASCII string representation of UUID v4 to the memory at given address.

I currently need support for rsa-sha256 signatures in u-boot and found out that
the code for signatures is not very generic. Thus adding of different

Many (but not all) of Blackfin boards give -O2 option
to compile under lib/ directory.
That means lib/ should be speed-optimized,
whereas other parts should be size-optimized.
We want to keep the same behavior,
but do not want to parse board/*/config.mk again and again.
We've got no choice but to invent a new method.
CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED, if it is enabled,
gives -O2 flag only for building under lib/ directory.
Dirty codes which I had marked as "FIX ME"
in board/${BOARD}/config.mk have been deleted.
Instead, CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED has been
defined in include/configs/${BOARD}.h.

When we tell the compiler to optimize for ARMv7 (and ARMv6 for that
matter) it assumes a default of SCTRL.A being cleared and unaligned
accesses being allowed and fast at the hardware level. We set this bit
and must pass along -mno-unaligned-access so that the compiler will
still breakdown accesses and not trigger a data abort.
To better help understand the requirements of the project with respect
to unaligned memory access, the
Documentation/unaligned-memory-access.txt file has been added as
doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1
tag of the kernel.

Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts:
scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
scripts/{Makefile.build,Makefile.host,Makefile.lib}.
This switch is triggered by the line in scripts/Kbuild.include
-build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
+build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj
We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.
Additionally, we need to fix compiler flags which are
locally added or removed.
In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.

This commit changes the working directory
where the build process occurs.
Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.
That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
$(obj)u-boot.bin: $(obj)u-boot
Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.
And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.
On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.
The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.
Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

Tegra124's MMC controller is very similar to earlier SoC generations,
and can be supported by the same driver.
However, there are some non-backwards-compatible HW differences, and
hence a new DT compatible value must be used to describe the HW. This
patch updates the driver to support that new compatible value.
That said, the HW differences are only relevant when enabling certain
high-performance transfer modes. Since the driver is currently very
simple and doesn't enable those modes, we don't actually need to address
any of these HW differences in the code yet, hence the simple nature of
this patch.

Commit 8dfafdde88eb ("Introduce common timer functions") created a
common definition of usec_to_tick() which had a couple problems:
static unsigned long long usec_to_tick(unsigned long usec)
{
uint64_t tick = usec * get_tbclk();
That likely overflows.
usec *= get_tbclk();
That was an attempt to fix it by performing the multiply after the
promotion of usec to 64-bit, but was applied to the wrong variable,
which was never used.
This patch fixes these issues. A user-visible symptom of the problem was
the e.g. "dhcp zImage" using an ASIX USB Ethernet dongle would print:
Waiting for Ethernet connection... unable to connect.
... with no delay before "unable to connect". There are likely other
symptoms.
