Some build scripts including scripts/Makefile.build
will be imported from Linux Kernel in the next commit.
We need to adjust them for U-Boot in the following commits.To make it easier for reviewers to track the modification,
this commit renames scripts/Makefile.build to
scripts/Makefile.build.tmp beforehand.Signed-off-by: Masahiro Yamada

We are going to switch over to Kbuild in upcoming commits.
Each makefile must have non-empty obj- or obj-y
to generate built-in.o on Kbuild.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 commit merges commonly-used header include paths
to UBOOTINCLUDE and NOSTDINC_FLAGS variables, which are placed
at the top Makefile.Signed-off-by: Masahiro Yamada
-
Before this commit, most of compiler flags were defined in config.mk.
But it is redundant because config.mk is included from all recursive make.This commit moves many complier flags to the top Makefile
and export them.
And we use new vaiarables to store them:
KBUILD_CPPFLAGS, KBUILD_CFLAGS, KBUILD_AFLAGS.
This will allow us to switch more smoothly to Kbuild.Signed-off-by: Masahiro Yamada

This commit adjusts some files to use Kbuild.include.
- Use cc-option defined in Kbuild.include
(Delete cc-option in config.mk)
- Use cc-version defined in
(Delete cc-version in config.mk)
- Move binutils-version and dtc-version to Kbuild.include
by analogy to cc-versionThis commit also adds srctree (same as SRCTREE)
to use Kbuild scripts.Signed-off-by: Masahiro Yamada

BFD_ROOT_DIR is used only in tools/gdb/Makefile

This commit moves some variable definitions from config.mk
to the top Makefile:- HOSTCC, HOSTCFLAGS, HOSTLDFLAGS
- AS, LD, CC, CPP, etc.
- SHELL (renamed to CONFIG_SHELL)I'd like to slim down config.mk file
because it is included from all recursive make.
It is redundant to re-define the variables
every time descending into sub directories.
We should rather define them at the top Makefile
and export them.U-Boot makefiles has been used "SHELL" variable to store shell
chosen for the user, whereas Linux Kernel uses "CONFIG_SHELL".We should never use "SHELL" variable because it is
a special variable for GNU Make.
Changing SHELL may cause unpredictable side effects
whose root cause is usually difficult to find.
We should use a generic variable name "CONFIG_SHELL".We should not use the syntax as follows either:
rm -f $(obj)tools/env/{fw_printenv,fw_setenv}
This depends on "bash" although GNU Make generally
invokes "sh" to run the each rule.Signed-off-by: Masahiro Yamada
-
This commit moves suffix rules from config.mk
to scripts/Makefile.build, which will allow us
to switch smoothly to real Kbuild.Note1:
post/lib_powerpc/fpu/Makefile has
its own rule to compile C sources.
We need to tweak it to keep the same behavior.Note2:
There are two file2 with the same name:
arch/arm/lib/crt0.S and eamples/api/crt0.S.
To keep the same build behavior,
examples/api/Makefile also has to be treaked.Signed-off-by: Masahiro Yamada

Some Samsung boards have their own tools under board/samsung//tools/.
This commit refactor more makefiles with "hostprogs-y".Signed-off-by: Masahiro Yamada
-
Before this commit, makefiles under tools/ directory
were implemented with their own way.This commit refactors them by using "hostprogs-y" variable.
Several C sources have been added to wrap other C sources
to simplify Makefile.
For example, tools/crc32.c includes lib/crc32.cSigned-off-by: Masahiro Yamada

This commit adds scripts/Makefile.host.tmp which will
be used in the next commit to convert makefiles
under tools/ directory to Kbuild style.Notice this script, scripts/Makefile.host.tmp
is temporary.When switching over to real Kbuild,
it will be replaced with scripts/Makefile.host of Linux Kernel.Signed-off-by: Masahiro Yamada

Ignore generated files by Kbuild such as .*.cmd, *.order, etc.
Besides above,
- Ignore *.s files
We do not need to ignore with file name, asm-offsets.s
- Do not ignore *.rej (for quilt)
- Ignore backup files, \#*#Signed-off-by: Masahiro Yamada

Add the SATA boot support for OMAP5 and dra7xx.
Renamed the omap_sata_init to the common init_sata(int dev)

Unlike other commands (for example, "fatwrite"), ext4write would
interpret the "sizebytes" as decimal number. This is not only
inconsistend and unexpected to most users, it also breaks usage
like this:tftp ${addr} ${name}
ext4write mmc 0:2 ${addr} ${filename} ${filesize}Change this to use the standard notation of base 16 input format.

This is much like a regular shell's -e operator, except that it takes
multiple arguments to specify the device type and device/partition ID
in addition to the usual filename:if test -e mmc 0:1 /boot/boot.scr; then echo yes; else echo no; fi

This emulates bash:
$ if test; then echo yes; else echo no; fi
noCurrently, the code sets expr = -1 in this case, which gets mapped to
0 (true) at the end of do_test() by the logical -> shell exit code
conversion.Signed-off-by: Stephen Warren

Currently, ! can only be parsed as the first operator in an expression.
This prevents the following from working:$ if test ! ! 1 -eq 1; then echo yes; else echo no; fi
yes
$ if test ! 1 -eq 2 -a ! 3 -eq 4; then echo yes; else echo no; fi
yesFix this by parsing ! like any other operator, and and handling it
similarly to -a and -o.Signed-off-by: Stephen Warren

This better mirrors the behaviour of bash, for example:
$ if test -z = -z; then echo yes; else echo no; fi
yesThis is parsed as a string comparison of "-z" and "-z", since the check
for the binary "=" operator occurs first. Without this change, the
command would be parsed as a -z test of "-", followed by a syntax error;
a trailing -z without and operand.This is a behavioural change, but I believe any commands affected were
previously invalid or bizarely formed.Signed-off-by: Stephen Warren
-
do_test() currently uses strcmp() twice to determine which operator is
present; once to determine how many arguments the operator needs, then
a second time to actually decode the operator and implement it.Rewrite the code so that a table lookup is used to translate the operator
string to an integer, and use a more efficient switch statement to decode
and execute the operator.This approach also acts as enablement for the following patches.
This patch should introduce no behavioural change.
