* Restrict flat format to architectures that support itAlexey Neyman2018-12-011-0/+1
| | | | | | Fixes #878 Signed-off-by: Alexey Neyman <stilor@att.net>
* Disallow linux versions before 3.7 for aarch64Alexey Neyman2018-09-291-0/+1
| | | | | | Fixes #1028 Signed-off-by: Alexey Neyman <stilor@att.net>
* Make comp.libs use generated templates, tooAlexey Neyman2017-11-291-0/+1
| | | | | | | | This allows us to include the component-to-package relation in the generated kconfig files and make use of that information in the show-config.sh script. Signed-off-by: Alexey Neyman <stilor@att.net>
* Super-H multilib toolchain fixesAlexey Neyman2017-09-031-1/+1
| | | | | | | | | | | | | | | 1. On SuperH, configuring GCC with explicit variant of the CPU (like "sh4") limits the default set of multilibs to just that CPU and requires --with-multilib-list to change. Allow for "unspecified" variant, so that we can defer to GCC to determine the list. 2. Support toolchains with both endiannesses at the same time. 3. Add a SuperH/newlib sample 4. Add more flags processing for uClibc Signed-off-by: Alexey Neyman <stilor@att.net>
* Switch gen-kconfig to new frameworkAlexey Neyman2017-07-081-1/+96
| | | | | | | | | | | | | | | Also: - Move companion_* to comp_* to match the kconfig symbols - Replace bootstrap with former gen-versions.sh - Fold *.in.2 into their respective first parts; this moves common options to the end - if it is undesirable, inclusion of *.in can be moved where *.in.2 used to be (but that will also move version selection after common options). - Retire addToolVersion.sh (may later replace with a more comprehensive script that tries to download the added tarballs, copy the patches and try to apply them, and create a version.desc).

* Allow --with-cpu/--with-tune for !arm.Alexey Neyman2015-11-141-0/+1
| | | | | | | | | | | | | | The configure error mentioned in the commits that disable --with-arch/--with-tune when --with-cpu is specified is specific to ARM builds. For other architectures, it makes sense (hey, it even makes sense for ARM - read 'info gcc'! - it is just a shortcoming of ARM build, apparently). Thus, add an arch setting ARCH_EXCLUSIVE_WITH_CPU (currently, set only for ARM) that will trigger current behavior. Permit combinations of --with-arch/cpu/tune for other arches.

* arch/arm: add support for AArch64Yann E. MORIN"2013-12-301-3/+4
| | | | | | | | AArch64 id the 64-bit variant for ARM. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr> Cc: Zhenqiang Chen <zhenqiang.chen@linaro.org> Cc: Michael Hope <michael.hope@linaro.org>
* arch/arm: ARM supports setting the floating point typeYann E. MORIN"2011-11-241-0/+1
| | | | Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr>
* arch: rename the SUPPORT_XXX optionsYann E. MORIN"2011-11-301-5/+5
| | | | | | | | | | | First, 'SUPPORT' should be spelled 'SUPPORTS'. Second, 'SUPPORT_XXX' really means 'supports --with-xxx', so rename the affected options accordingly. Update the affected archs to match the new namings. Reported-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr>
* arch/arm: ARM supports the softfp conventionYann E. MORIN"2011-10-191-0/+1
| | | | | | | | | | | ARM compilers can be built for soft float (software only, floats in core registers), hard float (uses floating point instructions, floats in FPU registers), or the half-way house softfp (uses floating point instructions, floats in core registers). Signed-off-by: Michael Hope <michael.hope@linaro.org> [yann.morin.1998@anciens.enib.fr: split the original patch] Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr>
* config: fix recursive depsYann E. MORIN"2011-05-081-14/+13
| | | | | | | | | | | The latest kconfig stuff is more stringent when it comes to validating the dependency of the symbols. It is no longer possible to have a symbol depend on itself (such as our construct for arch/cc/libc/... was doing). Fix our generated-file infrastructure to avoid these situations when the new kconfig stuff will be merged (in a following changeset). Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr>
* arch/arm: move config-options to second-partYann E. MORIN"2010-09-111-52/+0

* config/arch: always select the adequate bitnessYann E. MORIN"2010-01-091-0/+2
| | | | | | Even if the selected ARCH does not support different bitness (or we do not support building with another bitness), still select the appropriate bitness.
* arch/arm: add THUMB interworking supportYann E. MORIN"2009-10-261-0/+14
| | | | | | Add config option to build wtarget code with THUMB interworking. This is used to build the C library as well as all other code that runs on the target.
* arch/arm: add THUMB mode config optionYann E. MORIN"2009-10-261-0/+25
|
* arch/arm: add support for noMMUYann E. MORIN"2009-10-211-1/+2
| | | | | Some ARM cores do not have an MMU (eg. Cortex-Mx and Cortex-Rx series). Thus, allow the user to configure out the MMU for ARM.
* config/arch/arm: default to EABIYann E. MORIN"2009-10-211-1/+1
