* Makefile: remove a cleaning target "tidy"Masahiro Yamada2014-02-19-8/+3
| | | | | | | | | | | | Before this commit, "make tidy" did "make clean" + delete "*.depend*" files. But, we do not have "*.depend*" files any more, which means "make tidy" is the same as "make clean". This commit removes the redandant target "tidy".

* kbuild: generate {spl, tpl}-autoconf.mk only when it is necessaryMasahiro Yamada2014-02-19-23/+16
| | | | | | | | | | | | Before this commit, {spl,tpl}-autoconf.mk was always generated at the top Makefile even if SPL(TPL) build was not selected. This commit moves the build rule of {spl,tpl}-autoconf.mk from the top Makefile to spl/Makefile. It prevents unnecessary {spl,tpl}-autoconf.mk from being generated.

* kbuild: move include directives of board configuration filesMasahiro Yamada2014-02-19-15/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit changes the location of include directives of board configuration files. The purpose of this change is: - Slim down $(TOPDIR)/config.mk - Prevent $(TOPDIR)/Makefile from including the same configuration file twice - Do not include include/config.mk multiple times because ARCH, CPU, BOARD, VENDOR, SOC are exported Before this commit: - include/autoconf.mk was included from $(TOPDIR)/Makefile and $(TOPDIR)/config.mk (This means $(TOPDIR)/Makefile included include/autoconf.mk twice) - include/{spl,tpl}-autoconf.mk was included from $(TOPDIR)/config.mk - include/config.mk was included from $(TOPDIR)/Makefile and $(TOPDIR)/config.mk (This means $(TOPDIR)/Makefile included include/config.mk twice) After this commit: - include/autoconf.mk is included from $(TOPDIR)/Makefile and $(TOPDIR)/scripts/Makefile.build - include/{spl,tpl}-autoconf.mk is included from $(TOPDIR)/spl/Makefile and $(TOPDIR)/scripts/Makefile.build - include/config.mk is included from $(TOPDIR)/config.mk and $(TOPDIR)/spl/Makefile Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* kbuild: convert some make rules to Kbuild styleMasahiro Yamada2014-02-19-34/+43
| | | | | | | | | | | | We can get Kbuild-ish log style like this: GEN include/autoconf.mk GEN include/autoconf.mk.dep We do not need XECHO any more. And also change checkstack target like Linux Kernel. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

* kbuild: use Linux Kernel build scriptsMasahiro Yamada2014-02-19-325/+526
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | 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.

* kbuild: change out-of-tree buildMasahiro Yamada2014-02-19-744/+612
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: Gerhard Sittig <gsi@denx.de>

* Makefile: move more flags to the top MakefileMasahiro Yamada2014-02-19-37/+39
| | | | | | | | | | | | | 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 <yamada.m@jp.panasonic.com>

* Makefile: move some variable definitions to the top MakefileMasahiro Yamada2014-02-19-88/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Makfile: move suffix rules to Makefile.buildMasahiro Yamada2014-02-19-38/+34
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | 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.c Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

* cmd_test: implement -e test for file existenceStephen Warren2014-02-19-0/+6
| | | | | | | | | | 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 Signed-off-by: Stephen Warren <swarren@nvidia.com>
* cmd_test: evaluate to false without any argumentsStephen Warren2014-02-19-1/+1
| | | | | | | | | | | | This emulates bash: $ if test; then echo yes; else echo no; fi no Currently, 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 <swarren@nvidia.com>
* cmd_test: implement ! on sub-expressionsStephen Warren2014-02-19-19/+24
| | | | | | | | | | | | | | | 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 yes Fix this by parsing ! like any other operator, and and handling it similarly to -a and -o.

* cmd_test: check for binary operators before unaryStephen Warren2014-02-19-4/+4
| | | | | | | | | | | | | | | | | This better mirrors the behaviour of bash, for example: $ if test -z = -z; then echo yes; else echo no; fi yes This 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 <swarren@nvidia.com>
* cmd_test: use table lookup for parsingStephen Warren2014-02-19-67/+110
| | | | | | | | | | | | | | | | 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. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* fs: don't pass NULL dev_desc to most filesystemsStephen Warren2014-02-19-0/+16
| | | | | | | | | | FAT and ext4 expect that the passed in block device descriptor not be NULL. This causes problems on sandbox, where get_device_and_partition() succeeds for the "host" device, yet passes back a NULL device descriptor. Add special handling for this situation, so that the generic filesystem commands operate as expected on sandbox. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* fs: implement infrastructure for an 'exists' functionStephen Warren2014-02-19-0/+41
| | | | | | | | | | | | | | | | | | | | | | | This could be used in scripts such as: if test -e mmc 0:1 /boot/boot.scr; then load mmc 0:1 ${scriptaddr} /boot/boot.scr source ${scriptaddr} fi rather than: if load mmc 0:1 ${scriptaddr} /boot/boot.scr; then source ${scriptaddr} fi This prevents errors being printed by attempts to load non-existent files, which can be important when checking for a large set of files, such as /boot/boot.scr.uimg, /boot/boot.scr, /boot/extlinux.conf, /boot.scr.uimg, /boot.scr, /extlinux.conf.
