Since its introduction in7d8a59b40, the BR2_x86_geode CPU target has pointed to GCC -march=geode which targets AMD Geode processors [0]. This arch tuning enables MMX and 3DNow! extensions in GCC but these are not currently reflected in the selected flags by BR2_x86_geode. This is likely due to the confusing naming and history of "Geode". The AMD Geode can trace its origins back to the Cyrix MediaGXm [1] and then to the NSC Geode GXm/GXLV/GX1/GX2 [2]. All of these processors have MMX instruction support listed in their datasheets. The NSC GX2 was the first in the series to enable 3DNow!. When7fed07d3a4introduced BR2_X86_CPU_HAS_MMX, Geode was skipped presumably because it wasn't clear that the target is AMD Geode and because the Wikipedia documentation for Geode is incomplete [2] with regards to supported instructions as they all support MMX. Whenf6cd56b9ceintroduced BR2_X86_CPU_HAS_3DNOW, Geode was skipped presumably for similar reasons. Note: the in-tree olpc_xo1_defconfig uses BR2_x86_geode which is fine as this hardware uses the AMD Geode [3]. Make it more clear that the target is AMD Geode by renaming the Kconfig menu option and add both MMX and 3DNow! flags to BR2_x86_geode. This also means that BR2_x86_geode_mmx is no longer needed, and can be removed. No legacy handling is needed since BR2_x86_geode_mmx has never been part of any release.
