defaults are set right
|

After the addition of bare metal toolchains the menu system allowed
to create non-valid configurations. I reworked it so we can also
add other operating system support if we wish.
So first you choose your operating system, then your architecture
and endianess, after that your embedded system, emulator or
generic device and then you choose your task you want to run.
Tasks may be toolchain, a new appliance/application or some preconfigured
sets of packages and configurations as kodi, mpd, firefox and more.
The tasks are limited to a plausible choice of hardware and software.
Deduplicate CPU configuration.
You don't wanna compile Kodi for a H8/300 microcontroller ;)

Allows to choose which x86_64 CPU type should be used. The corresponding -march optimisation for gcc will be activated.

The new prereq check is completely implemented in
POSIX shell in scripts/prereq.sh.
It combines the old features from Makefile, scan-tools.sh,
scan-pkgs.sh, reloc.sh and some wrappers for tools.
The big benefit is to have all portability stuff in one place.
Furthermore we can compile GNU make and bash on the fly, for
systems lacking the required tools.
All changes on the host are detected on the fly, no make
prereq required anymore.
The build process is separated in following three phases:
1. small wrapper Makefile is used for BSD make or GNU make
2. prereq.sh is called, doing all checking, calling Makefile.adk
3. old logic in Makefile.adk or mk/build.mk is used
Tested successfully on Linux, MacOS X, Cygwin, FreeBSD, OpenBSD
and NetBSD.
An old depmaker bug was fixed, only optional host tools are compiled.
For example, even when a host provides xz, a local xz was compiled
in the past, because other packages had a build dependency on it.

We do not need to manually set mini.config file anymore.
Every target system, even Qemu emulating different models get
it its own. Cleaner and simpler to add new targets.

Add a more generic way to define CPU flavours for Toolchain
building. Add Cortex-A8 definition. Move Thumb symbol around.
|
|
After a short discussion with Phil, I put Libc stuff into
Toolchain menu, as it does not belong to Target configuration.
Add a Advanced Option menu for specific toolchain related options.
I think this change make building OpenADK for beginners simpler.
A starter doesn't know anything about different libc, floating settings,
...
|
|
ADK_TARGET_KERNEL_CUSTOMISING is set
|
|
|
|
Add new configs for uClibc-ng master.
New symbol UCLIBC_HAS_LINUXTHREADS added.
LT.new is removed in master, only LT.old and NPTL exist.
CLeanup MMU/NPTL/LT support symbols.
Tested with toolchain building for all supported architectures.
|
|
|
|
ARM, MIPS and PPC have support for soft or hard float configuration
of toolchain and system. Generalize the support for this in OpenADK.
|
|
Introduce new board symbols for embedded systems, which use
the similar board as basis. As for example raspberry pi and
raspberry pi2.
And some more updates:
Update binutils to 2.25, set gcc 4.9.2 as default.
Update glibc to 2.21, set as default.
Update gdb to 7.8.2.
Update kodi to latest release.
|
|
|
|
Binutils 2.24 is required to get a working kernel.
Ethernet in Qemu is still broken.
Qemu Patch is still rquired in 2.2.0.
Only kernel+initramfs is working.
It seems the signal handler problem is gone with
sash and simpleinit.

- Sync with Kernel upstream Kconfig
- use new feature visible
- add a patch for select on choices
https://lkml.org/lkml/2011/2/17/379
- rename ADK_LINUX -> ADK_TARGET_ARCH
- remove package collection feature
- add appliance feature to define a appliance
more complete
|
|
Use --with-cpu for gcc to have optimized code for
requested ARM cpus.
Add some basic support for cortex-m3.

Generate all data needed when adding a new arch or system.
Recognize any changes in target/*/systems as reported as bug by
Joerg.
