* ARM: rpi_b: rework boot scripts, enable sysbootStephen Warren2014-02-22-15/+70
| | | | | | | | | | | | | | | Rework rpi_b's bootcmd (and sub-commands) to match Tegra's bootcmd as much as possible. This will aid in a future patch which will create a common header e.g. config_distro_bootcmd.h. While at it, enable booting from extlinux.conf using the sysboot command. The iteration and componentization currently makes a little more sense for Tegra than RPi, but I'd still like to keep the two as similar as possible. USB and networking support is coming to the RPi in due course, and it'll all make more sense then anyway. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
* ARM: rpi_b: load /uEnv.txt from MMC at startupStephen Warren2014-02-21-0/+5
| | | | | | | | | | | The Pi has no flash to store an environment in the usual fashion. However, the user may wish to customize the environment. We know that the SD card must be present, since that's where the boot ROM has loaded U-Boot from. So, load uEnv.txt from there early during boot. This allows the user to e.g. customize boot_targets, in order to automatically select network boot. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
* ARM: rpi_b: convert to use distro defaultsStephen Warren2014-02-21-16/+13

* pxe: allow compilation when !defined(CONFIG_CMD_NET)Stephen Warren2014-02-21-0/+11
| | | | | | | | | pxe.c provides both the "pxe" command which relies on a network, and the "sysboot" command which doesn't. Fix the file to compile when network support isn't enabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike Linux Kernel, U-Boot historically had *.dts files under board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/. I think arch/$(ARCH)/dts dicretory is a better location to store both *.dts and *.dtsi files. For example, before this commit, board/xilinx/dts directory had both Microblaze dts (microblaze-generic.dts) and ARM dts (zynq-*.dts), which are totally unrelated. This commit moves *.dts to arch/$(ARCH)/dts/ directories, allowing us to describe nicely mutiple DTBs generation in the next commit. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fw_printenv is a program which mostly runs on the target Linux. Before switching to Kbuild, we needed to set HOSTCC at the command line like this: make HOSTCC=<your CC cross-compiler> env Going forward we can cross compile it by specifying CROSS_COMPILE: make CROSS_COMPILE=<your cross-compiler prefix> env This looks more natural.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We had switched to Kbuild, so we do not need to delete sandburst board files at every build. U-Boot conventional build system did not check the update of command line option, -DBUILDUSER. Kbuild can handle it nicely and re-builds object files when command line options are changed.

For example, the following did not work as we expect: $ make sandbox_config all Configuring for sandbox board... make: Nothing to be done for `all'. [2] mixed-target build did not work with -j option For example, the following did not work: $ make -j8 sandbox_config u-boot Makefile:481: *** "System not configured - see README". Stop. make: *** [u-boot] Error 2 make: *** Waiting for unfinished jobs.... Configuring for sandbox board...

Make targets are divided into four categories: - mixed-targets We can call a configuration target and build targets at one command line like follows: $ make <board_name>_config u-boot They are handled one by one. - config targets <board_name>_config - no-dot-config-targets Targets we can run without board configuration such as clean, mrproper, distclean, TAGS, %docs, etc. - build targets The other target which need board configuration.

| | | | | | | | | | | | | | | | | | | | | | | | 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".

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.

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>

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.

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>

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