toolchain-external: do not allow the user to select hard/soft float

2012-08-01T18:04:50Z

Commit ba92d6ef68eeb37ba435648fcfbd1dbe13212e6d made hard float the default when Cortex-A8 and Cortex-A9. The problem it was trying to fix is that the newer Linaro toolchains (2012.05 and 2012.06) are hard-float, so the default selection of soft-float enabled on ARM doesn't work for those toolchains. Unfortunately, not selecting soft-float causes problems with the Crosstool-NG backend at the moment. As an intermediate solution, make the soft float option disappear when using external toolchain: the toolchain will decide by itself whether to generate hard float or soft float code.

Simplify x86 target architecture variant handling

2012-07-30T22:00:29Z

Instead of having two separate list of choices for select the target architecture variant for i386 and x86_64, with many CPU choices duplicated (because all modern x86 CPUs can be both used as i386 or x86_64), merge them into a single list. In the x86_64 case, all the x86 CPUs that do not support the 64 bits instruction set are hidden. Signed-off-by: Thomas Petazzoni

toolchain-external: make preinstall the default for custom toolchains

2012-07-22T18:57:26Z

All the defconfig files used by the autobuilders that use pre-installed external toolchains are making the assumption that the default for a custom external toolchain is "pre-installed". We keep this default for now, since changing it breaks the autobuilders. Signed-off-by: Thomas Petazzoni

Make hard-float the default on Cortex-A8 and Cortex-A9

2012-07-22T14:53:52Z

Cortex-A8 and Cortex-A9 ARM cores are guaranteed to provide a hardware floating point unit, so there's no reason to default to software floating point for them. More importantly, the newest Linaro toolchains are hard float toolchains, so basically an user choosing those toolchains and leaving the default option of software float would run in compilation issues. So let's make hard float the default for Cortex-A8 and Cortex-A9. Signed-off-by: Thomas Petazzoni
