Author: Linus Torvalds
Date: Sun Mar 30 20:40:15 2014 -0700Linux 3.14
Needed for the MTD/UBI/UBIFS resync
Just copied the files from Linux, and added in the c-file
the "#define __UBOOT__" for adding U-Boot special code. In
this case we use this just for adding including U-Boot
headers.Signed-off-by: Heiko Schocher

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
With this patch, it boots again with CONFIG_SYS_GENERIC_BOARD
enabled.Signed-off-by: Heiko Schocher

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.Signed-off-by: Przemyslaw Marczak

This commit introduces cleanup for uuid library.
Changes:
- move uuidstring conversion functions into lib/uuid.c so they can be
used by code outside part_efi.c.
- rename uuid_string() to uuid_bin_to_str() for consistency with existing
uuid_str_to_bin()
- add an error return code to uuid_str_to_bin()
- update existing code to the new library functions.Signed-off-by: Przemyslaw Marczak

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.Signed-off-by: Masahiro Yamada

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.Cc: Albert ARIBAUD

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 objWe 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.Signed-off-by: Masahiro Yamada

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-bootHere, $(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 " 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="
syntax for descending into sub-directories.
(We can write it like "make $(obj)=" with a shorthand.)
This means the current working directory is always the top
of the output directory.Signed-off-by: Masahiro Yamada

This patch adds the bitrev library from the linux kernel. This is a simple
algorithm that uses an 8 bit look-up table to reverse the bits in data types of
8, 16, or 32 bit widths. The docg4 nand flash driver uses it.[port from linux kernel v3.9 commit 7ee32a6d30d1c8a3b7a07a6269da8f0a08662927]

Downloaded from http://slre.sourceforge.net/
and adapted for U-Boot environment.Used to implement regex operations on environment variables.
Code size is ~ 3.5 KiB on PPC.To enable this code, define the CONFIG_REGEX option in your board
config file.Note: There are more recent versions of the SLRE library available at
http://slre.googlecode.com ; unfortunately, the new code has a heavily
reorked API which makes it less usable for our purposes:
- the return code is strings, which are more difficult to process
- we don't get any information any more which sub-string of the data
was matched by the given regex
- it is much more cumbersome to work with arbitrary expressions, where
for example the number of substrings for capturing are not known at
compile time
Also, there does not seem to be any real changes or improvements of
the functionality.Because of this, we deliberately stick with the older code.
Note 2: the test code (built when SLRE_TEST is defined) was modified
to allow for more extensive testing; now we can test the regexp
matching on all lines on a text file (instead of the whole data in the
file as a single block).Signed-off-by: Wolfgang Denk

TPM command library implements a subset of TPM commands defined in TCG
Main Specification 1.2 that are useful for implementing secure boot.
More TPM commands could be added out of necessity.You may exercise these commands through the 'tpm' command. However, the
raw TPM commands are too primitive for writing secure boot in command
interpreter scripts; so the 'tpm' command also provides helper functions
to make scripting easier.For example, to define a counter in TPM non-volatile storage and
initialize it to zero:$ tpm init
$ tpm startup TPM_ST_CLEAR
$ tpm nv_define d 0x1001 0x1
$ tpm nv_write d 0x1001 0And then increment the counter by one:
$ tpm nv_read d 0x1001 i
$ setexpr.l i $i + 1
$ tpm nv_write d 0x1001 $iSigned-off-by: Che-Liang Chiou

isspace() and strim() are not in the typical user-mode string.h, so

This patch adds support for networking in SPL. Some devices are
capable of loading SPL via network so it makes sense to load the
main U-Boot binary via network too. This patch tries to use
existing network code as much as possible. Unfortunately, it depends
on environment which in turn depends on other code so SPL size
is increased significantly. No effort was done to decouple network
code and environment so far.Signed-off-by: Ilya Yanok

This library provides useful functions to drivers which want to use
the fdt to control their operation. Functions are provided to:- look up and enumerate a device type (for example assigning i2c bus 0,
i2c bus 1, etc.)
- decode basic types from the fdt, like addresses and integersWhile this library is not strictly necessary, it helps to minimise the
changes to a driver, in order to make it work under fdt control. Less
code is required, and so the barrier to switch drivers over is lower.Additional functions to read arrays and GPIOs could be made available
here also.Signed-off-by: Simon Glass
