The "project" feature was designed to allow to several projects to be
built inside the same Buildroot source tree and allowing the toolchain
and non-configurable packages to be shared between the different
projects on the same architecture. While being interesting in theory,
this feature adds a level of complexity to Buildroot, both from an
user perspective and from a developer perspective, while one of the
main Buildroot strengh is to be simple. Moreover, this feature is only
seldomly used by our users.
From a user-level perspective, this for example allows to remove the
project_build_ARCH directory, which was very confusing. The
autotools-stamps directory is also removed, since these stamps are
back at their normal location.
Description of the changes involved :
* project/, directory removed
* Makefile
- Don't include project/Makefile.in and project/project.mk anymore
- Grab a copy of the contents of project/Makefile.in at the
location it was imported, but remove the definition related to
PROJECT_BUILD_DIR. The TARGET_DIR is now in
$(BUILD_DIR)/target_dir
- Remove the creation/removal of the $(PROJECT_BUILD_DIR) and
$(PROJECT_BUILD_DIR)/autotools-stamps directories
- Don't make world depends on target-host-info. This target was
defined by project/project.mk to customize /etc/issue,
/etc/hostname and create /etc/br-version depending on the
project definitions. We can of course imagine re-adding such a
feature later.
- Replace PROJECT_BUILD_DIR by BUILD_DIR everywhere
- Remove the update, log and lognr.$(PROJECT) target, they were
specific to the project feature.
* package/Makefile.autotools.in
- Replace PROJECT_BUILD_DIR by BUILD_DIR for the location of the
configure cache
- Move the INSTALL_TARGET and HOOK_POST_INSTALL stamps to the same
directory as the other stamps (i.e, in the package directory).
* package/Makefile.in
- Replace PROJECT_BUILD_DIR by BUILD_DIR for the location of the
configure cache
* package/at/at.mk,
package/busybox/busybox.mk,
package/busybox/initramfs.mk,
package/customize/customize.mk,
package/linux-fusion/linux-fusion.mk,
package/ltp-testsuite/ltp-testsuite.mk,
package/nfs-utils/nfs-utils.mk,

target/ubifs/ubifsroot.mk
- Replace PROJECT_BUILD_DIR by BUILD_DIR
* target/device/Config.in
- Do not include project/Config.in anymore
* target/linux/Makefile.in.advanced
- Replace PROJECT_BUILD_DIR by BUILD_DIR
- Store the stamps file in $(STAMP_DIR) instead of
$(PROJECT_BUILD_DIR)/autotools-stamps
* target/u-boot/Makefile.in
- Replace PROJECT_BUILD_DIR by BUILD_DIR
- Remove $(PROJECT) from the U-Boot target binary name
- Remove the insertion in the configuration of the project name as
the hostname
- The u-boot-autoscript target now generates
$(U_BOOT_AUTOSCRIPT).img instead of
$(U_BOOT_AUTOSCRIPT).$(PROJECT)
* toolchain/gcc/gcc-uclibc-3.x.mk
toolchain/gcc/gcc-uclibc-4.x.mk
- Move the stamps files to $(STAMP_DIR)

u-boot 2009.06 changed the tools/ logic, and no longer adds symbolic
links to the needed library files in the tools directory.
Fix build by referencing the library files in their original location.

As discussed on the list.
- No sense in depending on BR2_TARGET_UBOOT when the configurations are
within a if BR2_TARGET_UBOOT conditional.
- n is default, so remove 'default n'
- clarify nested conditionals
Provide link using "u-boot.bin"
Add BR2_TARGET_UBOOT_DEFAULT_ENV config
If this is set, Buildroot will generate
a default environment to allow easy downloading
of the kernel and root file system
Both as compile time data and an autoscript.
Make u-boot depend on $(U_BOOT_TARGETS)
Add "u-boot-autoscript" to U_BOOT_TARGETS if
BR2_TARGET_UBOOT_DEFAULT_ENV is set.
Take kernel name from Linux build.
Use correct ARCH when mkimaging the autoscript.
Do not use TARGET_ATMEL_COPYTO for generic u-boot.
Hide dataflash memory configurations when
different boot memory is used.
More u-boot build unbreaking. r24646 added U_BOOT_TARGET which uses the
nonexisting BOARDNAME variable, which means that the filename expands
to -u-boot-*, confusing ln.
There's limited point in having that symlink in the first please, so simply
revert that hunk.
git-svn (and git) doesn't handle empty directories, so add .empty files
to those dirs like elsewhere in buildroot.
Those empty directories are normally not a big deal, but the recent changes
to u-boot broke the build.
mkimage the autoscript to autoscript.$(PROJECT)-
Move build of u-boot-1.2.0-atmel to target/u-boot
Only visible for AT91 targets.
Fetch prepatched 1.2.0-atmel tarball from $(BR2_ATMEL_MIRROR)
Rest from normal location.
Introduce U_BOOT_CONFIGURE_OPTS
Set to NOSOFT_FLOAT for u-boot-1.2.0-atmel
Disable target/device/Atmel/u-boot
Keep files in target/device/Atmel/u-boot during a test period.
Files:
M target/device/Atmel/Makefile.in
M target/device/Atmel/Config.in
M target/u-boot/Makefile.in
M target/u-boot/Config.in
A target/u-boot/1.2.0-atmel
